Ok so this is the scenerio. I have a P3 733 in an ASUS CUBX mobo, 512 SDRAM, 2x40G HD's, and an ATI AWI vid card. About a week ago the comp stoped working. It would not power at all, no fans nothing worked at all, I suspected it may be the PSU - because that didnt turn on eithr, so i got a new PSU but the problem remained. I started to take out component to see if anything else might be wrong - i managed to strip the mobo to the processor and one stick of ram but still nothing no PSU power up no mobo lights or sounds nada. I tried putting in my diagnostics card and it wouldnt work. I even went as far as replacing the actual power switch itself from an old working unit but still nothing. I am suspecting there is some kind of massive power failure with the board, but im not sure, i might of overlooked something - can anyone solve this puzzle?
