Clicking Sounds and Vibrations

This is another hardware issue. Noises like clicking, squealing, whirling or whining might come from damaged electronic components. Remove the computer case and let the computer run to see if you can find the problem. Save yourself some money and fix it yourself if you can, but your best bet is to call a technical expert if you're not confident with internal computer repair.

Lockups

Perform a few diagnostic steps to clean up spyware, which causes many system lockups. There are shareware anti-spy programs on the market that load the basic software onto your PC for free and have premium upgrades for a charge. Three reputable programs are Ad-aware, Cyber Patrol and Spybot.

Slowdowns

PC owners should regularly clean their registry, empty cache files and update software. Five-year-old machines are typically still in good order if diligent maintenance is done. Generally, a visit to Start/Accessories/System Tools (in Windows XP) does the trick. Disk cleanup and disk defragmentation usually take a few hours and are well worth the down time. The tools needed to check your system (computer management and system performance) are under Administrative Tools.

The screen looks like it’s on drugs

This problem is known colloquially as, “The screen is all messed up” or “My computer monitor is possessed.”
 
The psychedelic screen issue manifests itself in many ways, but the root cause is almost always a connection problem between the VGA cable and the VGA ports. 

When the VGA cable comes slightly loose, it causes the screen to glitch out in all kinds of wonderfully random colors, or display similarly spooky behavior. For this, the fix is so simple you don’t even need to be called out. 

If you are already on-site, you can always make a show of the solution so it sticks in the affected end users’ minds, allowing them to fix it themselves in future. Crack your knuckles and tell the end user to step back. Now, carefully wiggle the VGA connector and then slot it firmly back in the port. Ta da!

The computer is stuck in a restart loop

When the computer constantly restarts before getting to a login screen, a bit of troubleshooting is in order to make sure it’s not a software problem. 

Try to boot in Safe Mode. If it doesn’t work, or you can’t even select Safe Mode before it restarts, then it’s almost certainly a hardware fault. 

As many technicians can attest, RAM is the number one culprit. Essentially, the bootloader can’t load itself into RAM because the RAM has decided to take unofficial leave. The PC is able to power up normally, but it will constantly restart right before loading the OS. 

The fix: Power down the computer, open up the case, and reseat the RAM modules. If the problem persists, the RAM might be bad. Keeping a few spare sticks of common RAM types (DDR2, DDR3) in your toolbox is highly recommended.  

Now, if the restart loop is intermittent, but isn’t resolved by new RAM and you can still boot into Windows, here’s a tip for easy troubleshooting: Turn off Automatic Restart on System Failure. This makes the PC pause on the Blue Screen of Death so you can see the specific STOP error code. 

The Microsoft support page on STOP error codes is incredibly helpful in diagnosing which piece of hardware is faulty. Use it.

Insufficient Memory

Processor-intensive programs also demand a lot of memory. Random access memory (RAM) aides the central processing unit (CPU) by storing instructions linked to common operations. Without enough RAM, software crashes and slowdowns can occur.

Above mentioned are some of the commonly found PC hardware problems. However, these are minor issues and you can easily find a solution for it. As you can observe most of these issues are related to PC peripherals, for example Mouse, keyboard, USB camera etc. Hence, one of the root causes for these issues lies with your devices. Actually some devices need third-party software to be connected to the PC and even for its proper functioning. The software is referred as Device drivers. Drivers help the operating system to communicate with the hardware and helps in proper functioning of these peripherals. Even your video cards, keyboards, mouse, or any USB device plugged into the computer requires device drivers.

At times, these device drivers become outdated and hence, PC encounters any of the problems explained above. Most of the time updating your device drivers has resolved all your hardware issues caused by bad device drivers. So, you will have to find out an outdated driver and get the newer version of it and update the driver. In case all the drivers are outdated, then you need to download and update all the drivers in order to fix these PC hardware problems.

This is really a tedious process right. But, this is the only solution to get rid of these issues. One simple solution for this is Remo Driver Discover tool that could scan your PC thoroughly and locate all the outdated drivers. In addition, it even provides a single interface to download and update device driver in just few clicks. It is a time-savvy tool; you can make use of it or can do it manually that consumes lots of time. However, the best solution is to always keep updating your drivers to its newer versions and clean the peripherals regularly to avoid dirt that causes jumpy mouse and other problems.

Motherboard Problems

The motherboard contains several parts of the computer including the RAM, BIOS system, mass storage and CPU. The computer motherboard contains several devices, which can create numerous potential problems. Problems with the motherboard range from too little RAM to BIOS problems. Fixing the problems will depend on the specific problem and, in the worst case scenario, purchasing a new motherboard will fix the problems.

Power Cord Problems

Whether it is a laptop or a desktop, power cords are a vital part of any computer. The desktop needs the power cord to work. A laptop can run on batteries for a limited amount of time, but then needs the power cord for recharging. The most common problem with the power cord is an improper connection.

Keyboard Problems

As we all know the keyboard is a vital part of any computer. It not only allows typing, but it also gives commands as well. However, you might encounter some common potential problems with the keyboard that includes keyboards that will not connect to the computer, stuck keys, broken keyboards or keyboards where the letters end up jumbled.

My smartphone will not synch with my PC

In order to ensure backup of your smartphone, it is important that you regularly synch your phone content with your computer. At times, your PC might fail to sync with your smartphone. It can be due to many reasons. Sometimes it is required that all programs are closed, during synching or backup.

PC won’t recognize my USB camera

In this case, even when you connect your USB camera, you PC might not be able to recognize it and hence throw errors like “Device not recognized” error. This might be due to the USB connector problems or the software malfunctioning. Before plugging in the camera, turn it on. This action can usually solve your problem.

Jumpy Mouse

Jumpy Mouse! Sounds strange right?  Actually, a jumpy mouse is just a muted mouse i.e. cannot be scrolled. If you have a track and ball mouse, then simply turn it over and open the ball container, and remove the excess debris and clean the dirt that lines the rollers. For an optical mouse, eliminate the dust that has collected around the optical sensor.

Mouse Problems

The mouse is used for a variety of purposes, such as playing games or opening files and moreover, it facilitates easy navigation, thus easy access to your data. The most common problems related to the mouse include failure to move, connection problems, freezing on the screen or damage to the mouse.

Blank monitors

A blank monitor is the most common computer problem. Most people who work with computers might have dealt with such non-working blank monitor at least once. In such cases, first and foremost check the supply cord and power systems. Sometimes, the video cable might be loosened. Just push the video cable and place it again, it should help your now.

Loss of an Important File

You have been creating a PowerPoint presentation for 15 days. A day before the presentation, you find it missing from its location! Hold your breath, may be you have moved it to some other folder. Go to Start menu and type the name of the file and observe the results. If nothing appears, then there’s a possibility that the file has been renamed. At such situation, again go to Start and type a word that was in the presentation. Hopefully, this will bring better result. However, if you didn’t get any result, then search in the Recycle Bin as it can possibly be deleted by you accidentally. Don’t worry, as you can restore your data from backup.

Missing Administrator Password

If a person leaves your organization without revealing the password applied to his/her computer, then all the data saved on his/her PC becomes inaccessible. Fortunately, you can recover the password applied to your computer through password reset disk, another account on the same system with admin rights, or last but not the least, through third-party password recovery tool.

Your PC Doesn’t Boot

Many of you encounter situations in which your PC becomes completely unbootable. At such situation, you should try booting your system with Windows recovery disk. However, if you do not have CD/DVD of your Windows recovery disk, then you can borrow it from someone. In case, if your PC is not even booting from the CD, then go to its setup screen and change the boot order. By doing this, the CD/DVD drive or optical drive appears before the hard drive. After this, you will get an onscreen message telling that you have to press a particular key ‘for setup’.

If your system boots, then follow the prompts. Most likely, the utility will tell you what the problem is and ask whether you want to fix it or not. You do. However, if it doesn’t ask you, or if the disk is unable to fix the problem, then you’ll find a menu with various options. You can either use Startup Repair or System Restore.  Now let’s take another case, in which your PC fails to boot before entering to set up or booting from CD, then there is some hardware problem. At such situation, you have to go to the data recovery service professional.

Beeping coming from INSIDE the computer, but everything is fine

This problem is known colloquially as, “No, it’s not coming from the speakers. The box is literally beeping at me.” 

It’s easy to forget that desktop PCs have a speaker inside the case. It beeps once every time the PC is powered on as part of the Power-On Self-Test (POST). I mean, who actually turns off their desktops?
Aside from that friendly chirp announcing a successful boot, the onboard speaker will lurk silently in the inaccessible depths of the computer casing, until that one day when it has something urgent to say. 

When insistent beeping starts coming from inside the computer while it’s running normally, it is often accompanied by appropriately alarmed end users — which is good, because the main purpose of the built-in speaker is to alert nearby humans in the most annoying way possible that the CPU is running too hot. 

It’s telling you, “Hey! I’m dying here. Can you please slow down, or I don’t know, open a window?”
It might not be catastrophic if you fix it immediately, so after you’ve explained that the box is not beeping because it’s about to explode (which is technically true), take these steps:

• Enter the BIOS and note the CPU temperature. If it’s over 140 degrees Fahrenheit (60 degrees Celsius) then it’s getting too hot for comfort.
• Ensure the CPU hasn’t been overclocked by an enthusiastic end user.
• Check that the computer case is well-ventilated and all fans are spinning.
• Blow out the dust on the motherboard and system fans. Do this outside!

If the computer isn’t booting at all and emits only a short series of beeps, it’s time to break out the BIOS beep error codes for the motherboard. This will tell you which piece of hardware is failing, and how.  

Or you can just Google it.

The system clock keeps resetting back to days gone by

Date and time is important to a computer, and the wrong date and/or time can cause a host issues that appear to be software-related, such as broken software licenses and confused browser cookies.

To an end user, this looks like the end of the OS as they know it. Luckily, it’s a cinch to fix. 

The motherboard’s CMOS battery, which powers the onboard Real-Time Clock (RTC), is too low or dead, and needs to be replaced. 

In practically all motherboards, regardless of brand, it’s a ‘CR2032’ 3V button cell battery. 

Keep a stash of these batteries in your Geek Bag and make this common hardware issue a non-issue.

My favorite program isn’t working on my new PC

Before you call tech support, make sure that the software you’re trying to run is compatible with your operating system. Older software might not function on Windows 8, and an app created for Mac OS X definitely won’t run on your Windows PC. A 32-bit program might run on your 64-bit operating system, but it doesn’t work the other way around.

Not all file types work on Windows. For example, files that have the .app extension run exclusively on Mac OS X.

If an online game balks, you might be missing the required plug-ins—Java and Flash are the usual culprits. Most browsers will alert you to install these items if necessary.

I can’t open email attachments

If you have ever encountered an attachment that you couldn’t open, it was probably because you didn’t have the software necessary to view the file.

If you don’t have Adobe Reader or another PDF-compatible program, you won’t be able to open that TPS report.

The usual suspect is the .pdf file, for which you can download a free PDF reader. If your problem involves a different file format, a quick search on the attachment’s file extension (the three letters after the period in the filename) should tell you what type of program you need. If the attachment lacks a file extension (which might happen if it was renamed), adding it back should set things right.

My printer won’t print

Let’s assume that your printer’s drivers are up-to-date, and that it has enough paper and ink or toner to print. Try turning the printer off and on. Unplug the printer and plug it back in. Check your printer’s print queue by looking for the printer icon in the system tray and double-clicking it. The print queue shows you the status of each job as well as the general status of your printer.

The print queue is your best bet for troubleshooting printer problems—just make sure that ‘Use Printer Offline’ isn’t selected.

Ensure that ‘Use Printer Offline’ isn’t checked. Sometimes, printing while your printer is turned off can cause Windows to set your printer to work offline, and that can stall jobs sent later.

I keep seeing ‘There is a problem with this website’s security certificate’

Sometimes the biggest problems have the easiest fixes. According to support technicians, the lion’s share of issues are due to an incorrect system clock.

The problem is probably with your computer.

Website security certificates sync up with your computer’s clock. Old computers in particular run the risk of having a dead CMOS battery—the watch battery in your computer that keeps its system clock ticking. Click the clock in the system tray and select Change date and time settings to correct any issues.

Google doesn’t look right

Browser hijackers are a particularly nasty breed of malware. Such programs take over your Web browser and can stealthily redirect your Google searches and other queries to fake pages meant to steal your personal information or to further infect your system.

Running a real-time antivirus utility is the best way to stay safe. If your browser has already been hijacked, uninstall the browser and use your antivirus program in conjunction with Malwarebytes to remove the intruder.

Pop-up ads are appearing on my desktop

If you’re not running your Web browser and are still getting pop-up ads on your desktop, you’ve most likely installed adware—a program that displays unwanted ads. Although benevolent adware exists, most of the time adware is up to no good. Getting rid of it isn't easy. “There’s a ton of little system-utility tools out there that promise to clean up everything, with names like PC Speed-up, PC Speed Pro, PC Speedifier,” Geek Squad’s Meister says. “A lot of times those programs are not going to do much. Some programs will work, others are snake oil.”

Avoid downloading programs that offer to speed up your PC or clean up your registry. Instead, use a trustworthy adware scanner like the free version of Malwarebytes' Anti-Malware tool.

Running a full scan with credible antivirus software is your first step. If that program doesn’t find and remove the adware, turn to Malwarebytes Anti-Malware Free, a great utility for removing all types of malware. Just make sure to disable your standard antivirus software before running it.

“Multiple antivirus programs working at the same time will often result in problems,” Falcon Northwest’s Petrie says. “You only want one active, real-time antivirus scanner installed, but it doesn’t hurt to run an additional ‘on demand’ virus or malware scanner.”

Searching online for the name of the advertised product can sometimes yield solutions from fellow victims. If all else fails, there’s always the nuclear option: a complete system reinstall. It might take a long time, but it’s the only surefire way to remove adware or spyware. Remember to back up all your personal files.

Downloads are taking forever

Speedtest.net is your best friend when you're having connectivity problems. Run a speed test to see what your download and upload speeds are—ideally they should be at least 50 percent of your Internet service provider’s advertised speeds, with a ping under 100 milliseconds.

If the speeds seem solid, make sure that you aren’t inadvertently downloading or uploading anything. Many torrent downloading programs run in the background and minimize into the system tray instead of the taskbar.

A good speed test should give you an accurate assessment of your ping, download speed, and upload speed.

Check your network hardware. Updates for network cards aren’t all that common, but if your card’s manufacturer offers a newer driver, download it. Resetting your router and modem can help with connection problems, too. Most routers and modems have reset buttons, but pulling the power cable for a second or two can do the same thing. Don’t cut the power for much longer, or the hardware may reset itself to factory defaults.

Still having problems? Call your ISP, which can tell you whether the problem is on your end. As a last-ditch measure, the ISP could reset the master connection to your home.

My computer is too slow

The first step to fixing a slow computer is to verify that your machine is the actual source of the problem. Videos that seem to buffer forever, and websites that take ages to load, may not be your computer’s fault. Geek Squad agent Derek Meister claims that many people mistakenly identify a slow system as the problem when “it’s actually not the computer, [but] their broadband connection.” See “Downloads are taking forever” below for instructions on how to use Speedtest.net to diagnose a slow connection.

If the problem is your PC, check whether you have plenty of free space on the hard drive holding your operating system. Windows needs room to create files while your system is running. If your hard drive is maxed out, performance suffers. Now is the perfect time to clear some space.

If your computer’s operating system resides on an overstuffed C: drive, clearing out some space could boost OS performance.

Microsoft’s System Configuration tool is your next-best bet for tackling slow performance. Many applications launch automatically when your machine boots up, which can stretch out boot time—especially on older, slower PCs. Make a habit of trimming the startup items. Open the tool by pressing Windows-R, typing msconfig, and pressing the Enter key.

Checking the Startup Item and Manufacturer columns is the best way to figure out which potential performance-killers you can safely disable. Avoid messing with any of the services and programs that have Microsoft Corporation listed as the manufacturer. Items such as AdobeAAMUpdater, Google Update, Pando Media Booster, Spotify, and Steam Client Bootstrapper are all fair game. Regardless, err on the side of caution: If you’re not sure what the program or service does, don’t disable it. 

Windows’ System Configuration Tool lets you disable programs and services that automatically start when you boot your computer.

Once you’ve made all your changes, click OK and restart the computer. It should boot up quicker and feel noticeably faster.

Applications Not Installing

If an application or piece of software is not installing on your computer, it typically means one of two things. Either the application is not compatible with your particular operating system, or the software has requirements your computer does not meet.

Always compare the minimum system requirements necessary to run software with the specs of your computer. If you don’t meet those requirements, then you simply cannot run the program without upgrading. This is rare, but it can happen. Most of the time the software will still run, but it will do so poorly. There is the off-chance that it won’t finish the installation process, however.

In the first case — where software is not compatible with your OS version — there’s not much you can do. You can try and look for a compatible version of the software you want to run, or you can look for an alternative.

Fix Overheating Problems

The best way to deal with an overheating issue is to monitor the temperature inside your computer case or chassis and then take action. If the CPU or processor is overheating, you likely need to reseat the chip by coating it with new thermal paste and installing a new fan. If it’s the GPU or graphics card, you’ll likely need to replace the card — but in some rare cases, you can have it repaired or sent back to the manufacturer for a replacement.

You can use a tool like Open Hardware Monitor to check the temperature of components inside your computer.

If the temperature inside the case is getting too hot and it’s causing everything to lock up — which is not as common but still happens — then you’ll want to install case fans inside the chassis. You can also rearrange components and hardware inside the case, so there’s enough space for air to flow in and out.

Bypass a Frozen Screen

If the screen freezes, there’s only one thing you can do. You should immediately press CTRL+ALT+Delete and choose the “Task Manager” option if a menu appears. If it does, simply close the app or process that is frozen. If that option doesn’t work, then you’ll need to power cycle your computer.

This shouldn’t be happening often. If it is, it’s generally a sign of more severe hardware issues like failing components or overheating.

How to Deal With Hard Drive Failure

Unfortunately, hard drive failure is bound to happen eventually. As drives are used to read, write and erase files, the components inside wear down. The worst part is that there’s never usually a way to tell when it’s going to happen. Yes, you can run diagnostics on a failing drive and see signs, but when they appear, the drive could die right then and there, or it could still have months of use left.

When a hard drive fails, the only way to fix the problem is to have it replaced. You can do this yourself by buying and installing a new one, or you can take your computer to a shop — but that will be much more expensive.

The trick is to make sure your personal data is always backed up. You can do this by regularly copying or backing up files to an external or alternate hard drive. That way when the one you’re using fails, you still have the backup data to moved to your new drive.

If you do not create backups — or even don’t perform them regularly — there’s a real possibility you will lose valuable data if and when a drive fails. That can include important documents, passwords and accounts, photos, videos, media content, game saves and more.

Troubleshooting Internet or Network Connectivity Issues

Another common problem that can cause a lot of headaches is internet connectivity. This can be an issue with your ISP, locally with your router and other hardware, or even software related with your computer. Sometimes even just restarting Windows can fix a problem.

If you want to check your internet speeds, you can use a tool like Speedtest.net. You can also use the Windows network diagnostic tool to check for local problems, like driver or wireless card failures.

Remove Malware

The best way to deal with malware — and prevent it — is to keep a malware tool on your computer and updated at all times. Keep in mind malware tools are separate from virus software. Sometimes a security suite will include tools that can screen for viruses and malware, but they are not the same thing.

One of the best malware tools you can find is MalwareBytes Antimalware. There is both a free and premium version, though the features do differ.

Malware can often hold your computer hostage — this is also called ransomware — or slow it down by using up system resources. Spyware is also a problem, which is similar to malware except it collects sensitive information about you like bank account numbers, passwords and more.

Malware, spyware, and viruses need to be dealt with immediately if and when you encounter them.

Applications Running Slowly

A computer slowdown that causes apps to run poorly is extremely common. However, this is not an easy fix because there are so many factors that could be contributing to the slowdown.

For example, your computer may need more RAM, or random access memory, to handle processes better.

A computer can also experience slowdown if a hard drive is full — often this is the main hard drive on which the OS is installed and runs. But a failing hard drive or one nearing the end of its life can also cause significant slowdown.

Then there’s the number of apps and processes you have running. Google Chrome, for instance, is notorious for eating up a lot of system memory and resources because it keeps so many processes open.

First, you need to pinpoint what is causing the slowdown. The best way to do this is to duplicate the problem by shutting everything down and opening apps and processes one by one.

Open the Windows Task Manager by holding CTRL+ALT+delete and then choosing the related option. The Task Manager windows will appear. Make sure you are looking at the “processes” tab. Here, you can see all the apps that are currently running on your computer.

Start shutting down the apps you have started — or even some that have automatically started — but do not close any system intensive tasks. You’ll know right away if something is system intensive because an error window will appear asking if you really want to close that process. Obviously, when that happens, you’ll want to refrain from doing so.

Once you are confident, all the user apps are no longer running. Open your apps and tools one by one and check to see if there’s slowdown. This will allow you to find the culprit.

Replacing Missing DLL Files

A DLL file is essentially a unique function that developers can include with their applications. These files contain instructions for the computer and OS (operating system). If one of these files is missing, it can cause a lot of problems, especially since there are so many of them.

The best way to deal with missing DLL files is to rely on the System File Checker — an integrated Windows utility. It will scan the system files on your computer’s main hard drive and check to see if anything is missing or corrupted. It’s entirely possible for files to exist, but they might become corrupted over time. This can even happen if a hard drive is starting to fail.

The System File Checker will scan all the necessary directories and will replace or repair files as needed.

You can also use your Windows install CD or installation ISO to manually copy the DLL files needed, but this is a lot more complicated.

Monitor goes black after few seconds

If the monitor goes black after few seconds of display, then it could be a problem with the color quality or screen adjustment. Press the auto-adjust button on your monitor to see if it fixes it. If not, then you will have to change display color from 32bit to 16 bit.

You can connect the PC to another monitor to adjust colors from your graphics card settings. Pressing the auto-adjust may show the display for few seconds. You can use this to your advantage and adjust the color while pressing auto-adjust.

PC isn’t powering on

If your PC is not powering on at all – not even a single light in it, then it must be a problem with the power source.

Desktop users: If your PC’s extension cord, power outlet, and other connections are working fine, then the problem may be with the PC’s power cable. Replace the power cable of the monitor with the CPU’s (if you don’t have a spare) to see if it turns on. You’ll have to get a new power cable if this fixes the problem.

Laptop users: Take out the battery and put it back before starting the laptop. If this doesn’t work, then take out the battery again and connect the charging cable to the laptop. Start the PC on charger power and see if it works. You will have to replace the battery if it fixes the problem.

Note: You should also remove all types of external devices connected to your PC while trying this. A malfunctioning device might cause this issue.

PC crashes before loading the OS

If your PC only shows manufacturer logo and then crashes right before it was supposed to load the operating system, then it’s a problem with RAM or hard disk. As the OS is unable to load, then either the RAM is corrupted and can’t hold the boot loader or the hard drive is damaged and can’t load data inside it.

If you have multiple RAM slots, then taking out each one of them one by one and starting the PC will help find the culprit. In the end, you will have to replace the corrupted RAM or the hard disk, whichever has the issue.

Overworking fan

Your PC fan runs according to how much your PC is heating. The higher the temperature, the faster the fan will run. In case your PC temperature is fine (you can use HWMonitor to check it), but the fan is running at full speed; then you’ll have to manually control it.

You can use the SpeedFan app for this purpose as well. It will tell you the running speed of all the fans inside your PC so you can manage their speed. Don’t worry about app compatibility, overworking fan problem only happens with motherboards that can control the fans.

PC beeps

Each time you start the computer, the BIOS conducts a power-on self-test (POST). If the computer freezes or otherwise fails to boot, the CPU may be unable to communicate with one or more hardware components. The cause may be a faulty component, faulty installation or a problem with the BIOS. During the POST, a series of beeps may sound an audio code to indicate what problem has occurred. Most PCs beep once at the successful completion of the POST, some beep twice.


The meaning of the code will depend on what brand and version of BIOS is used. Furthermore, motherboard and computer manufacturers will sometimes modify the BIOS and associated codes. The table below describes the general case failure associated with the beep code for the three most popular BIOS'. Be advised that because of a lack of standardization, your beep codes may not match this table.

PC keeps disconnecting from WiFi

If your Wi-Fi is working fine but your PC keeps disconnecting from it, then your PC’s network card may not be receiving full power. Windows has a built-in power saver option that gives less power to the network card. You need to disable this feature:

1. Go to Advanced settings in the Power Options.
2. Here expand Wireless Adaptor Settings and then expand Power Saving Mode.
3. Set this to Maximum Performance.
