A few months ago, my computer did not boot properly. Instead, it boots off and on and after a period of time, it finally starts and I can use my computer without problem. I only had to press the on/off button once. That 'period of time' has gone on to be longer, from seconds to nearly one minute now.
This week, things has gone much worse. Now, I have to press the on/off button more than one time. Also, when I want to turn off my computer, it 'updates' and than the computer reboots all by himself (not even finished with updating!). I basically have to turn it off twice Today, I've finally reached the boiling point when my computer has reboot itself randomly many times today, even after I turned off the automatically restart function by system failures. There's nothing in my minidump file and there are no BSOD.
I have absolutely no idea what to do, can anybody help me?
