Kernal Power Event 41

Second time this happened... Started 10 days ago while i was doing nothing but typing a word document, then stopped. But last night as I was running a pcmark vantage test it crashed again and rebooted =(. I already tried disabling the auto reboot on crash thing and didn't work out. I also ran a memtest86+ and found no errors the first time.

Anyways heres the error
