Just upgraded my mobo to asus p9x79 pro running windows 7 on wd 1tb hdd. I have corsair vengeance 4x4gb mem sticks and radeon hd 4850 card along with 600w psu. When i tried to boot up after install, I can get to the bios just fine but when windows trys to load i see the splash screen for a second and then the blue screen flashes for a fraction of a second and the boot process cycles again only this time it tries to repair windows but cannot. Can anyone help?
