It could be a driver issue as suggested earlier - have you updated your motherboard drivers in the last year? Also you may benefit from a BIOS update if not already done so. It might also be worth opening up your case and checking all components, especially memory, are firmly in place. Give it a quick once-over for dust, too.
By the way, no-one's mentioned, virus, spyware scans etc - do a comprehensive one, and defrag your drive.
