[gilmey]

Hello,
i have a weird problem-it started a few days ago my computer turned on by itself in the middle of the night -for a few days ... and idea what can lead to this?
so i turned the switch off in my power supply so it wouldnt turn on again
then a few days ago my computer suddenly didnt turn on at all
so i took out the cord from the electricity put it on again after a few minutes and then it worked again
but today my computer doesnt turn on again! -i tried to take the power off and then on but it still doesnt work
i see a light in my mb and i see the numbers 0.0. (i have an ip35 pro motherboard)
i checekd the abit site and the code means "ready to boot"

From the sounds of it, I would guess the psu is having issues.

PSU or Motherboard.... I would test by using a different PSU with more power that you know works. Next I would check to make sure nothing is broken on the board.
