I've been having a lot of problems with crashes/ram dump errors lately. More-so the Crashes. My sytem will shutdown anytime I try to run video, burn cds, pretty much anything other than general web browsing/word processing. I have no idea where to start with this. I have formatted/reinstalled XP, and that didn't help. I've swapped video cards, nothing... Could it be a faulty HD??? (its getting old) Please....someone...anyone...HELP ME!!!
