For some reason, my computer blue screened on me while starting up a game, and i had to restart. It's happened before, except now, it won't go past the initial Dell loading screen. I've tried using the windows disk to boot and that didn't work. I don't know what to do. i have a dell xps 600. It'll start on the initial dell screen, and won't go past that. Pressing f2 or f12 just freezes the thing.
