Problem with My PC


Thread Starter

Hello Guys, I just need some help regarding a new problem that my PC has.

When I was using the computer, the power went out. After it came, I tried to open the PC and the following happened:
-Pressed the power button
-The power LED turned on
-The HDD LED Also turned on, but turned off after 2 seconds.
-No signal on the monitor.
-The light in the mouse turns on.
-The keyboard doesn't respond to caps-lock or Num-Lock keys (The LEDs do not turn off or on).
-The PC remains on forever, but nothing else happens. Inside, only the fans turn on. I also realized that a cracking sound my PC usually makes (I suspect it is from my hard drive) is no longer there.

Does this mean this is a problem from my hard drive? Or there is a more serious problem my PC has? (Like a motherboard or a VGA card failure)
Can A Hard Drive Failure cause such a thing?
Also, are there any DIY fixes I can make? (I have ejected and placed the RAMs multiple times, also removed and put back the CMOS battery, but to no avail)

Please I need answers.
Thank you very much!

A pw surge can cause many problems with electronics ie motherboard, processor, pw supply, etc, etc. The only way you are going to find the cause is to test your parts in a bench or test system OR swap known good parts into your system.
I would start with the pw supply. Note you do not have to fully install a test unit. You can simply connect atx, aux/cpu pw, and video pw [if used] Hit the ON button and see if the motherboard will complete POST. If it does, install a new pw supply. If it does not complete POST, then you will need to swap other parts ie motherboard, etc.

If you don't have one to try you can remove the psu easily and take it to a shop for testing they won't charge you much. It's 4 screws and a bunch of plugs then carefully pull it out of tower.
