Well, I went out earlier, and when I got back, the PC was broke. The story behind it is that my dad had thought the PC was on sleep mode, when it was actually just a black screensaver. So he pressed the OFF button on the PC, since it usually wakes the PC up. So obviously, at this point, the PC had started to shut down as it was just a screensaver. About 15 minutes later, the PC was still shutting down, so my dad held the OFF switch. Then, when he tried to switch the PC back on, there was an error saying something about the registry file being missing or corrupted. The instructions say to reinstall Vista with the disk, but we don't have it anymore. Are there any other methods of fixing this problem that don't require a disk?
Also, for those of you wondering how I have access to the website atm, I'm using my laptop.
