To help you troubleshoot common PC problems yourself, I have listed most common PC hardware problems and solutions if you face any of them.

 1.Dysfunctional USB Port

If your USB port stops working, it’s not necessary that it’s broken. Below are some solutions that can fix this issue:

Method 1: Restart the PC

Restarting the PC is the answer to many problems, and it is a common solution to USB port problem as well.

Method 2: Uninstall USB port driver

Uninstalling the driver of the USB port will force Windows to reinstall it when you will restart the PC. This may fix the problem. Here is how to do it:

  1. Press Windows + R keys and enter devmgmt.msc in the Run dialog to open the Device Manager.
  2. Here, expand Universal Serial Bus controllers option.
  3. Now right-click the entry USB Host Controller and then click on Uninstall.
  4. Repeat this for all entries with USB Host Controller to uninstall drivers for all the USB ports.
  5. Once deleted, restart the PC and Windows will automatically reinstall the drivers and fix any driver issues.

Method 3: Disable USB selective suspend

USB Selective Suspend is a Windows power saving feature that suspends unused or idle USB ports to conserve power. Sometimes it could stop a USB port from working. Here is how to disable it:

  1. Press Windows + R keys and type powercfg.cpl in the Run dialog to open Windows Power options.
  2. Here click on Change plan settings next to your current plan and then click on Change advanced power settings.
  3. Now, expand USB settings and disable USB selective suspend setting.
  4. Restart the PC to see if it fixes the USB port issue.

Note: This option should be kept enabled if you want to save battery power. If it doesn’t fix the USB port issue, then enable it again.

PC Overheating

heating PC slows down the whole system and leads to frequent crashes. Additionally, PC components may also get permanently damaged due to constant exposure to heat.

There are two main reasons your PC heats up, i.e. either the cooling system isn’t working properly or the PC is heating to the point your cooling system can’t handle it anymore

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.

PC beeps

The PC motherboard is smart enough to detect problems and sounds beeps in different rhythms to tell you.

If the PC doesn’t start after the beeps, then it’s usually difficult to solve the problem yourself. However, I’m going to list down two of the most common problems due to which beeps occur, and thankfully, you can solve them yourself as well.

Problem 1: Out of place RAM

A problem I recently dealt with. If the RAM inside your PC gets loose or out of place, then your PC will beep 2-3 times and won’t boot at all. The solution is simple, open up the PC (laptop users should let an expert handle this) and reinsert the RAM. Here’s how:

  1. Take out the RAM completely and clean any dirt inside the slot using a cotton bud.
  2. Now insert back the RAM and put enough pressure on both ends to ensure it is fully inside.
  3. Afterward, close the clips and make sure they’re properly locked. Even a slightly loose RAM will be unable to work.

Problem 2: Recently added hardware

A damaged or wrongly installed hardware component could lead to beeps. Take out any newly added hardware components and see if it solves the problem. If the PC works fine afterward, then either get it installed properly or get it fixed (or replaced).

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.

9. 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.

10. Noisy PC

If you hear a lot of extra noise while using the PC, then most probably it is a plea to clean it up. Get it cleaned or use a can of compressed air or leaf blower to clean it up yourself. If you have overclocked your PC GPU and CPU, then they could be the reason for the noise as well.

Blue Screen of Death

The dreaded Blue Screen of Death (BSOD) can occur due to both software and hardware problems, but usually, it’s a hardware problem. Whatever the cause, BSOD requires immediate attention as it’s a sign of a big problem.


Bluescreen view  is a great Nirsoft utility that will show important information if you have recently suffered a Blue Screen of Death. You should be able to identify and solve the problem using this information. Below are some common reasons for BSOD and their solutions.

Corrupted drivers

A corrupt driver may be the cause of BSOD. To find that out, use the following steps:

  1. Open Device Manager by typing devmgmt.msc in the Run.
  2. Here expand each menu and look for a yellow triangle icon next to each driver.
  3. If you find any, right-click on it and select Update Driver Software to update its driver.
update driver

You can also use a third-party app like IObit Driver Booster to automatically find and fix driver problems.

2. Too much pressure on the RAM

If you open too many programs that RAM can’t handle, then it may freeze the system and show BSOD. For that, you should either stop opening too many programs or upgrade the RAM.

3. Faulty hard disk

BSOD is also a sign of a dying hard disk, use the instructions in problem #11 above to identify hard disk problems.

4. Heating PC

Heating PC also leads to BSOD if too much pressure is put on the components. Use the instruction in problem #1 to solve it.

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.

15. Keyboard issues

If your keyboard is making noise and won’t type repeated words properly, then there is no problem with the keyboard. You must have enabled toggle keys and filter keys in Windows settings that cause such a problem. To disable them:

  1. Open the Control Panel and click on Ease of Access.
  2. Here click on Change how your keyboard works button.
  3. Now uncheck the checkbox next to Toggle keys and Filter Keys to solve this problem.

In Conclusion

Many of the above hardware problems can be easily fixed by tweaking the settings or using a software. However, some of them will definitely require you to pay a visit to the computer repair shop.

It’s good to at least know what is wrong with your PC so you can take the measures accordingly.
