This morning I got on my computer and went about what I usually do. All of a sudden my mouse locked up and the screen went blank. It came back on in safe mode, said it recovered from a device driver failure and wanted me to restart. Since then, it has happened about 4 more times. I did a scan, checked to make sure all drivers were up to date, went to Microsoft and updated stuff there, did a virus scan and it is still doing it. I also went to PC Pitstop and scanned there. Can anyone tell me why this keeps doing this?
