My PC has a mind of its own, it shuts down by itself at times. Then restarts, and everything is fine. I have been checked out for malware by somoen on the malaware forum, they cleared me. I have checked to see if it is an overheating problem, and its not, I have two fans and they are both functioning properly. I have not added any new hardware that I know. I get no error messages when this happens.
Please let me know
