I've got a weird problem - when I start my machine up, it turns on for a second, turns off, then turns on again and then gets to the POST check. After that, everything is fine. I can stress test, play games, everything just fine. It's just that weird first boot. I believe this only happens when overclocking it, I don't recall this ever happening when I was running on stock speeds. Any clues or steps I could take to get rid of that first boot?
