I have a computer that was working fine until one day it stoped booting up.
When I press the power button I have no respond. fans off, no power LEDs, no thing.
The only thing that turns on is a usb + SD-RAM reader in the front of the case indicating that there is power to the board.
I tried replacing the PSU, power switches, power cable, nothing.
There is also nothing wrong with the motherboard, no burs, no thing strange at all.
