My 350w power supply burns out and so i've replaced it with a 450w one. But now i get this hanging thing going on when i'm doing stuff. For example, Oblivion was running smooth as hell before but now it's choppy whenever i move( if i don't move, the other npc's seem to run smoothly). And even when i'm clicking on the winamp in my task bar to make it appear and disappear it can take up 100% of my cpu and lags for 3 seconds or so.. Obviously some piece of hardware on my comp is dmged from the faulty psu, i'm just not sure which one. any ideas?
