i'm not sure where i should put this, mods move if need be. and no pc flamers (pc sucks type posts) either. i'm currently having a major pc problem running xp (this could end the pc days for good, as i'm in the progress of migrating the rest of my pc work to my macbook, a year long process). for the past few weeks, my pc has been restarting at the strangest times, first, it was just after working on memory intensive programs. but over time, the restarts got worse and the restarts happen when i'm checking my mail or some other normal task. my computer is slowing down gradually, taking longer to respond to the mouse and keyboard. i've been also hearing strange buzzing noises from the tower, and i'm not sure where it's coming from. i've pretty much ruled out a virus, since i've ran a virus check in the past week and put me with a clean bill of health. i personally think the hard drive is failing, but someone else said that the motherboard could be going down as well. can someone help me figure out why my computer keeps having these restarts? thanks.
