How to Repair Computer

Follow this step by step approach to exactly diagnose and repair computer.

Repairing your computer yourself can be manageable if you follow some simple steps, if you are aware of some basic computer terms and programs.

I am listing you step by step simple steps to check and repair your computer problem. 

Although the subject is vast, I have tried to list the most important things that you should check for.

If your PC is not booting at all - Check the following steps.

1. Check the power cable

2. Check the spike or ups if its ok

3. Check the Hard disk and power on lights

4. If they are on, then check if the monitor light is on or blinking

5. Check for boot up beep sound. If you hear a beep sound then the system is booting ok and you might have a problem with your monitor.

6. If there is no beep sound, check if your SMPS or Power supply is working. (See if the fan is rotating) You can see that on the back of your computer cabinet.

7. If the smps is working and still there is no beep sound, then there might be a problem with your Ram or Memory. Try cleaning the RAM slot and the RAM chip. You can even try to shift the RAM to an empty slot if available.

8. Check your small internal pc speakers if they are working. (you might not have heard the beep sound if the speakers were not working)

9. Try removing all add-on card in your motherboard PCI slots and starting the system. Sometimes one of the cards might be damaged and this might be the cause of PC boot error.

10. Check your CPU fan if it is working fine. Also see if the fan is rotating fast enough. If the fan rotates slowly, the fan ball bearing might be damaged and this might cause the CPU to heat up excessively and it might have been damaged.

11. Check for any physical burnt or swelled up capacitors on your motherboard. If yes, then the motherboard must be repaired or replaced.

12. Check for any loose connections of your card slots, wires and power cables inside the cabinet. Try to exchange the power cables with another part. (eg remove the power cable of the harddisk and insert in CD-ROM and vice-versa)

13. Also look if the motherboard is touching the cabinet tray. If yes, the power is sort, and that is why it is not booting.

14. If you are aware of the computer parts and have some basic knowledge, you could even try to dismantle all parts and assemble it again. (What we refer this is as "Open Set-up")

15. If you have followed the above steps correctly, you may at least have diagnosed the exact problem.

Hope the above helps to identify and correct the problem. I have tried my best to explain you the steps.
