Hey guys. I just upgraded from S775 to 1155 and purchased an i5 2500k, Asus P8P67 (rev 3.1), 2x2GB G.Skill DDR3 1600, Corsair HX750w. Everytime I shutdown my computer (whether its for 30 seconds or over night) my computer will not power back on on its own. I have to kill the power from the PSU via the switch for 5-10 seconds, flip the switch back on and it boots right up. This becomes a pain in the ass after a while and I was wondering if anyone has had any other experiences with something happening like this and what you did to solve it (if at all). The really weird thing is, whenever I have to use the above method to get the computer to turn on, the BIOS gets reset to factory default when I never touch the CMOS battery or jumper. Thanks for the input guys!
