OK.. so my computer is around 6 years old. It is a dell. I year ago, I changed the hard disk from 20 gb to 120 gb. It worked fine. Now, since I have a new computer, I decided to replace the old computer with the 20 gb and install the 120 gb one in my new computer. However, now I can't start the old computer at all. When I turn on the power, the motherboard doesn't seem to be getting power. If it is getting power, the four lights on the back should light up, I think..

I contacted Dell a while ago, and we fixed it by resetting the processor. But, now the problem is back. No lights, no display on the monitor..

Is the motherboard broken or what?

Can some one help me? It would be highly appreciated!! Thank you.

It would be extremely difficult to diagnose whether this problem is a motherboard, the power supply or wiring remotely.
You may have disconnected something when removing or replacing the hard drive.

Try making sure all the connections are tight, even the power cord and the wires to the on switch on the front of the case.

Do you have a meter that can check voltages?

Hm... the only disturbance that I can think of that can be caused by resetting the cpu has to do with the heatsink. But, on the motherboard, do you know the jumpers which make power possible for the whole computer? (check out your motherboard manual, if you don't have one, look on their website) Also making sure that that the powersupply is doing well and good would be a good idea, course you need a meter for that sort of thing, but I can only think of a few things that can cause this, and my first guess is the unlikely possibility with the jumpers. a computer should still be able to boot up even without a processor, if it had to do with the battery it would have given a checksum error, if it had to do with security features, it should work by unplugging the computer for 15 seconds, and then plugging it in again and trying to start the computer. (this is still a possibility) lastly there is always the possibility that it could be a bad motherboard... which COULD have happened when you installed the new hard drive, and a static discharge... but that wouldn't explain why resetting the processor would work... ah well good luck
