Starting a month or so ago, my computer started rebooting randomly. Before that, I leave my computer on all the time and its never an issue. So i thought it might be my cpu overheating and I cleaned it out. It worked okay for 2 days but just now it randomly rebooted again. Could it be a memory problem? I don't think its a HD issue since it doesn't blue screen of death on me and no weird HD clicking either. I am pretty confused...
