well trust me when i tell u if u have the same problem after replacing the cpu..its something else. look at everyone else here who has the same hardware. other than swapping out parts...i dont know what else to suggest as i dont think it could be a corrupt windows install. u have 7 64 bit? if u do i had to reinstall mine once due to it not booting after a bios update. im just trying to shoot from the hip here with suggestions
to help...sorry ur having to go through this i know how frustrating it can be
