BSOD -> sounds like XP -> run your "manage" / "logs" log and check for all HALT (! - exmplamation in red triangle or so) notes... if there is anything about soft or hardware problem - if it is soft problem, check for viruses, if hardware problem -> check for your heat pipes/ vents, remove dust from CPU/ Video card cooling systems... if no go, try old good reinstall OS ... I try to kick my PC thrice (magic works, especially on xmass) but this is not official advise
