okay so heres the story. i left my pc on today while i was away, and it turned out to b a pretty damn hot day and on hot days my room gets insanely hot. so i got home and my pc was acting all funny, its lagging wen opening multiple programs and even wen im just talking to people on msn and listening to music. i think something might have overheated a bit. im thinking it might b my memory, what do you guys think?
