Computer won't turn on - symptoms
So I went to turn my machine on today, and it powered up for about 1 second then shut right off. I tried turning it on again for another 5 minutes, and it only turned on again once, for another second, then shut right back off. I'm guessing the power supply is shot? The light on the motherboard is on so it is receiving sufficient power, which doesnt make much sense to me. ANy help would be great thanks.
