i was playing medal of honor allied assault and it started running all wierd and then it just froze and the system restarted! this happened before when i was playing sonic heroes demo. when the computer reboots (it does this automatically when this problem happens) i get a message saying "your computer has recovered from a serious error". what does this mean? im running nvidia geforce fx 5500 pci, 1024 mb RAM, 120 gb seagate HD, celeron D 2.6ghz. im able to have the settings on high for most of my games, and they run fine, minimal stutter. i think it might have been an overclocking error, as i have my card slightly overclocked, but when it happened before and i was playing sonic heroes, the card had never been overclocked, and wasnt overclocked at the time. what might have caused this error? any help would be great, thanks!
