Hi, I figure that I'll ignore my old problem, and focus on this one. I decided to use my backup cds to get my laptop back to normal, however whenever I try to do this its overheat and shut down in the middle of process. It don't do this when I use another OS. I tried cleaning the fan, but only made 25% process. Any suggestions ?

That's weird...does the fan even come on? If it does, does it make a rattling sound?
Another possibility is to elevate the laptop so it's not sitting flat on any solid surface, that can sometimes result in overheating
