I have an Alienware Aurora R4 with Windows 7 Home Premium 64-bit that's been acting pretty wonky. It's had issues booting, when it does boot it eventually slows down and crashes and the check disk from the boot seems to find a bunch of corrupted files. I am assuming that all I need to do is to repair windows 7. Problem is, the version of Windows 7 is not compatible with my version when I try the "repair windows option". What should I do?
