Troubleshooting Common Hardware Problems

1

We come across a number of problems while using digital devices. For example, your computer can stop running at any time if it gets stuck somewhere, may be one part is not working properly or other part needs to be repaired. After all, it’s just a machine!

Then we call upon a technician for solving these problems. But there are minor problems that we can resolve ourselves and we must be aware of troubleshooting these common problems.

Below are listed some common problems and their related troubleshooting:

1) Keyboard Problems   

 If wrong characters appear on the screen while you are typing with your keyboard:

  •  It may result from improper connection. Check first whether the keyboard is connected well with the computer or tighten the loose  connection.
  •  There might be a problem in the installed keyboard driver. Re-install it and check if it works.

 

2) CD/ROM Problems

When you insert your CD/DVD, it is not read by the computer:

 The CD/DVD driver may be causing problems. Try to re-install the driver or get a new one.

 

3) Monitor Problems

When you start your computer, the monitor is blank:

Try to first find where the problem is. Disconnect devices from your computer like CPU, Printer, and Scanner etc except keyboard and mouse. Now, start the computer. If it has started and the screen appears, this implies the disconnected devices are causing problems. This helps in giving a little information about where the problem is.

If your screen looks bad:

  •  Restart your computer and run it in safe mode. You can do this by pressing F8 at the time of starting your computer.
  •  Reinstall monitor in the device manager and see if it works fine now.

If the screen has been rotated:

It shows the problem is in Graphic Controller. Go to My Computer, choose properties, go in settings tab, select advanced, choose graphic properties and click on rotation tab.

4) Sound Problems:

Reset the default BIOS settings: Switch on your PC, press F1. When BIOS set up appears, press F5. Select ok and press F10. Again press ok. Exit BIOS set up and restart your system. Check if the sound works well now.

5) Video Card Problems:

 If the screen resolution is changing every time you start your PC:

 The video card installed in your PC might need to be updated.

 To check which type of video card is installed in your PC:

Go to run and type “cmd” to open the command prompt. Type “debug” and press enter. Then type “DC000:0010” and press enter. It will give the information about the identifier of your video card.

6) USB Problems:

If you have upgraded window to vista and insert your USB, it changes from 2.0 to 1.1:

You need to upgrade the installed driver.

If USB flash driver works on one computer and not on another:

 Go to My Computer, select manage, then select disk management. Check if a drive letter is assigned to it or not. Assign it if it’s not assigned.

 Safely remove icon is missing:

 Right click and select properties. Uncheck hide and inactive icons and click ok.

USB is not recognized:

 Go to device manager, select properties and enable “Write Caching”.

7) Battery Problems:

 Your computer gives dead battery errors:

 It shows your battery is dead and you need to replace it.

Standby mode does not work:

  •  Check if power manager is enabled or not. If not, enable it.
  •  Uninstall any third party applications or USB inserted in the CPU.
