My suggestions: First and foremost, update the bios for the love of god! Chances are that will fix it. If nott, take the stick that caused issues, even minor, out. No reason not to, as you can run fine without it and just stick it in later, if the problem is something else. Next, I would try an older video card in place of the 9600. If that all fails, I'd be suspicious of the mobo itself. Just my thoughts.
