Well, I had my settings as shown in the screen shot, turned on the computer and left for work, found it off when I came home. I haven't turned it on tonight, but I turned on AIDA logging a few days ago, logging every 30 seconds, just to mainly get a ballpark idea of what time it turned off.
I'll leave the settings as is for now and pull all external devices, and plug in the plainest USB KB & mouse to see if that does anything. (as opposed to the gaming KB & mouse I'm using). Running out of things to try. If you thought it was something SSD, I could image to a HDD and use that for a system drive to test, or I could still try those 4x2GB Dominators that I didn't have issues with in my P55 system.
