XPS8300 Continuous power cycle on start
I am running the Dell XPS8300 on Win 10. Occasionally when I first start up or during a period of hibernation the computer will go into an unending cycle of fan ON and after 2-secs OFF. This repeats continuously until I hold the power button down for 10-secs and then disconnect the power cord for 30-secs. If I then hold the power button down for a second or so until the activity light illuminates then release everything boots perfectly. During sleep or hibernation the same thing occasionally happens and the only way to recover is to hold down the.n power button for 10-secs and disconnect the power cord. What's going on and can it be fixed by someone technically challenged :-)?
