I just built my first system, and i turned it on loaded win 7 ultimate, and right off the bat i got a blue screen, but then it seemed ok after a restart, then in the bios i overclocked the cpu just a bit from 2.8 to 3.4 i have a liquid cooling system by the way. then i kept getting blue screen errors , so i tried to reinstall the os, and now it wont install any os at all. it blue screens in the middle of the install.
