I am on a Windows XP based AMD Athlon XP eMachine and I am using firefox and installed Service Pack 2. Recently I have noticed about once a day or every few days the PC immediately powers down out of nowhere and restarts...and everytime it has happened I have been on Myspace.com, I don't know if it is a coincidence or it is because of myspace...but what should I do? Once it restarts it says....you system has just recovered from a serious error. I am on myspace sometimes a lot so it may have to be some bug....but should I take all my files off my PC and restart all over? thanks in advance. (edit) I recently got this and it hasen't always done this...just recently.
