I got a cd key from a school deal for free for vista pro. i can install it properly on a new hard drive (1000 gigs) and then every time i go to run it i get this error and the blue screen. 0x0000007e (0xFFFFFFFFC000000, 0XFFFFF8000985E251, 0XFFFFF98001AF6428, 0XFFFFF98001AF5E00) When i go to repair it says nothing is wrong. I have also downloaded a new cd and burned it and tried again but I'm still getting the same thing. Any suggestions?
