If it's the same model number and bios type there shouldn't be a problem. I mention the bios because compaq, HP, emachine, etc. sometimes use the same model motherboards but their bios is different. XP--and I assume, Vista--won't accept a different branded bios.

What makes you sure it's the Mobo? What are the symptoms?

Power supply testers are not real accurate. Did you try it in a different machine? Does the Mobo light come on? I'm assuming it doesn't post either.

Actually you have to have the exact part number and revision number to be exact. It could be that you would need to fix the hal or add/remove a few drivers.

As above, did you test the power switch and did you read how to use a paper clip to test power supplies?

Why did it take me over a year to phone in a problem to ATT?

If you did the paper clip did the unit power on? Did you see any keyboard lights or other indications? Could it be that the power switch is bad or cable to mb for switch is bad?

I unplugged the power supply from the mobo so only the fan came on in the power supply. The computer never came on.
