I’ve never had this problem before but for the last 2 month my computer has been randomly shutting off all on it’s own. Then when I try to immediately turn it on again it doesn’t work – trying to power on for 2-3 seconds then dies again. If I wait for 5-10 minutes and then try it’s like nothing ever happened (no errors just an unexpected shutdown message on my browser) almost every time it’s happened while I’m using Firefox. Is it a hardware problem(overheating?) or is there something else i should check?
