I keep my computer on sometimes over night. I kept it on for two nights, and when I got back from work, it had restarted itself for an unknown reason. Then it happened again two days later. I'm guessing there is something with with the Nvidia GeForce 5700LE drivers again because I have had nothing but problems since I installed it. Is there anyway to find out what is causing my computer to restart? Are the errors saving on a log on my computer? No critical error messages pop up once my computer restarts. I have the option to automatically restart upon system failure turned OFF in the device manager, so I really have no clue what is going on.
