A client computer here at work continues to restart when it is left alone for a few minutes.. I have checked the power options and everything there is set to never. He said it only happens when he goes to lunch, or leave the computer idle for a few minutes and then he comes back and the login screen is there and everything needs to load up again. Also, I made sure hibernation was set to off.. Should I run HijackThis on the client computer?? What else can i check to try and sort this problem out?? Thanks in advance!!
