I'm having an odd problem I would appreciate some insight to. Built a new rig back 8 months ago; everything was working fine and dandy, when all of a sudden I can't turn my machine back on after a shutdown or it goes into hibernation. I've tried cleaning for dust (there was a bunch), turning the PSU on/off at the back of the computer; no dice. Checked inside the computer and cables all seem to be in place. The only thing that works is to physically unplug the cord from my outlet and plug it back in - once I do that it fires up like normal (nothing over heating, no strange sounds). But again, if it goes into hibernation/shut down I can press the power button and nothing happens. It doesn't turn on for a few seconds with a few beeps - it's as if the computer isn't plugged in at all.
Once I unplug-replug and use the computer everything works fine with no hiccups
Any insight would be much appreciated. Build is below:
SAPPHIRE 100351SR Radeon HD 7970
G.SKILL Ripjaws Series 8GB (2 x 4GB)
Seagate Barracuda 1TB Serial ATA Hard Drive
SeaSonic G Series 550-Watt
