Computer constantly crashes.
Alright, so I'll start my story from the beginning.
I was playing WOW when all of a sudden it crashed to windows and a really weird error message popped up. I don't remember what it was exactly, but anyway my computer restarted but Windows Xp would NOT load up, it would just constantly restart. I ran system restore and instead of loading up, it left me a message saying, "Windows is not properly installed." Frustrated, I gave up.
I decided to try it again a week later and found that Windows finally booted up. About an hour later, my computer restarted and did the same thing over again.
I thought maybe it was overheating, so I removed the side to let it get extra air. My fans seem to working ok, but there is a lot of dust. Do you think this was an overheating issue or is it something else altogether?
Thanks for the help.
