Well, its a Toshiba P25-S507 and it only happens when I am playing video game for like an hour or two (Call of Duty, Doom3, Need For Speed Underground 2) and when I am tryint to copy and burn a DVD-Movie. It didnt start doing this until the last month. I took it back to best buy and they had for like 3 days and they told me nothing was wrong with it. I plan on calling Toshiba tonight to see what else I can do. Right now, when I play a game of burn a DVD I turn my desk fan on low and it doesnt shut off.
