Okay, well it's become out of hand, so I've sent it away, and apparantly, its full of dust and animal hair, (my dog), and that is what caused the excessive overheating and also, apparantly they think the problem is with the MoBo, but I'm keeping a close eye, as I don't want to be ripped off for something that could be a lot cheaper and less complicated than replacing the whole motherboard....
Well, I'll keep this thread posted with updates, and it may help other people that have problems like this, (not brand dependant),
