I'm using a GA-Z68XP-UD3P (rev 1.3; UEFI ver: U1e) with a 2600K, and when I perform a cold boot after the computer has been turned off for several hours, it won't even POST. It goes into the boot loop for 5-8 boots before bringing me to a screen that says it won't POST. Sometimes it will boot successfully after the 5-8 loops, though. I've tried removing the batter and clearing the CMOS, but nothing has changed. Anyone know a trick?
