I have a emachine T6216 when I start it up and it goes to windows it shuts down. Sometimes at the start of windows sometimes 20 mins later. When I restart it the temp is 40 degrees centergrade (144 degrees F). If I go to set up I can stay there a long time more then 20 mins, I also ran recovery and it went all the way through then when it started to run windows it shut down. Pulling my hair out here. There is no set time it shuts down sometimes 20 mins sometimes shorter. Does any body have any iders?
