ok, my pc has just suddenly started freezing for no apparent reason. first of all when i open things like wmp etc or even youtube to watch vids and stuff it jams. the whole screen and mouse freezes and i have to reset. also happens when i open msn up and look at the main bit too long (20 seconds or so) and when i open my hotmail it also can possibly jam its really starting to get on my nerves.... at first i thought it could be a hardrive problem cos i heard creaking when i started pc up... but after re-formatting each of my 3 drives they all do the same. so it cant be them?? please help -- any help appreciated , - thanks.
