So I've got a bit of an issue. When I walk away from my PC for an extended period of time >1hour, the screen goes dark and the computer will not wake up. Typing on the keyboard, moving/pressing the mouse, and even pressing (not holding) the power button will not send any video input to the screen. Also, when I unplug my USB keyboard and mouse and plug them back in again the devices no longer power on (both devices have multiple lights on them and none light up). The only way to get back to my PC is to hold the power button and then power it on again. Interestingly enough, after powering down the pc from one of these incidents, it takes anywhere between 5 to 10 seconds from me pressing the power button to the PC actually powering on (fans start spinning, lights come on, etx).

Once I am in windows (7 64bit), it is perfectly stable. I ran prime95 and furmark following one of the incidents with no issues whatsoever.

This is becoming quite a problem, if anyone knows what is wrong, please let me now.

System specs:
i5 3570k (OC 4.2GHZ)
msi z77a-g45
2 x4g kingston 1600mhz ram
700 watt OCZ mod x stream pro PSU
7950 Sapphire
500 GB HDD (WD)
64GB SSD (Mushkin)

You should take a look at the Power Options (find it in Control Panel). I'm guessing the PC is set to hibernate after a set time of inactivity.

After it hibernates it should wake up after a short click on the power button, so there is a problem there. It could be that you don't have enough space on the SSD for the hibernation file, and that the PC therefore locks up when it tries to hibernate.

The easy solution is to set the PC to never hibernate in the Power Options.
