I have a custom-built PC using Windows 7 Ultimate 64-bit. After I come home at night or get up in the morning while leaving my computer on during the day or night (i.e., computer has been on and idle for ~8hrs), I find that the computer has entered some sort of sleep mode from which I cannot awaken it. I moved the mouse, pressed every key on the keyboard (keyboard LED came on when I did that), and I pressed the power button as well. Eventually I had to switch off the power supply. Upon reboot it says "Resuming Windows..."
I thought I had turned off hibernation (Set it to Hibernate After: Never)
This is super annoying.
Anyone know how I can prevent this in the future?
