I have amd phenom with 4 gigs of memory in gigabyte mb. I checked and double-checked all components, and everything seems to be in order. Couple weeks ago I tuned on my pc and got a blue screen after geting halfway through the four color microsoft logo animation (bunch of zeroes with ERROR). Since then I havn't been able to boot, reinstall windows(it stops midway informing that files are missing on a dvd), or repair it. Any suggestions?
