So I build my friends pc and everything was going smooth for months. Until one day he was in a rush and shut down the computer, and as it was in the process of shutting down (windows xp) he hit the light switch on his wall and shut the computer off cold prematurely. This has never really caused a problem before. But for some reason this time, triggered something bad. Cause I can't get into safemode even. Tried all different settings but every time it goes to boot up, and restarts right away when it gets to the windows xp loading screen. When you try to boot normally there's a quick flash of an error message (blue screen) but I can't see what it says, restarts too fast. Any ideas on what could have gone wrong?
