At 7 years it's anyone's guess what's wrong with that board. I know some may cringe but motherboards are too cheap to dwell on here. A hour of tech time can be more than the board so if you feel it's the board, try another.

Hi guys, i had an old pc, im using it since 7 years as a server testing pc. I was using it yesterday, and suddenly turned off, and never turn on again. I dissarmed all the pc, and connect the psu to the motherboard and try to start the motherboard manually. When i start the pc, for 0.00001 second the cooler and the lights start, but then it turns off. There is none flawed capacitor or something like that. I think there is a short circuit on the motherboard. I tried the psu with other pc, and works perfect, the ram is not important, because i start the pc without the ram (For testing the pc, the ram is not important i think). What could be?
