To fix this, I opened it up, cleaned the fans and heat sinks, and reapplied thermal paste, which was a dry crumbling texture. But after putting it back together, and turning it on, the display seems to just not work, it boots, just doesn't post anywhere, I've tried 2 different monitors, one of which I am using now. I have no battery in it (stopped working a while ago), and really no other place to turn to. So if anyone has an idea, I would be willing to try it.
