MajkY: You're not alone. A couple of us in the P5Q thread on [h]ard have the same problem, though mine isn't quite that bad. The only advice I can give is to reflash your BIOS, clear CMOS, load default settings, and definitely do not load any saved OC profiles, create fresh ones. After doing all that sometimes the problem returns after 4-7 days but for me it's mostly fixed. Now and then it crops up, maybe 1/50 or 1/100 times I save BIOS settings. I really want to know what triggers it as it seems random on my board.
