Normally i would post this on CPU forum. But i thought i would try out my new favorite website.
So the problem,
I built a computer probably 3 years ago. (DFI Mother Board, Thermal Power Supply, 4 512 western memory, 300 western hard drive)
It sat enclosed in my garage for a 10 months while i was away.
The first attempt to run the computer was trouble, all plugged in i turned the power switch on, the motherboard lights turned on, but the POWER switch on the motherboard was useless. I then unplugged and cleaned reconnected everything. Now the computer turns ON all fans turn on, It seems about to run. But the monitors wouldn't turn on..... Also my fan control works, but non of my drives work, NO CD, NO Floppy (yes i have a floppy)

Any Advice???
My possible thoughts are, hard drive is dead.

Does it beep? When and how many times? When video doesn't work I believe you should hear an extra beep. Also, no video wouldn't have anything to do with the HD. Try a different monitor? Also, if you have access, try a different video card.

Also, did you take OUT the motherboard to clean it? I had a similar problem along those lines due to the motherboard being grounded in the case.

Some motherboards need extra power from the power supply. There is a 4 (or 6 or 8) pin connector on the motherboard, which you need to connect to the correct plug on the power supply. This is used to power the video card. If you haven't plugged it in, the motherboard still works, but the video card doesn't.
