So my friend brought me his laptop that restarted ever 30 mins or so. I booted it into safe mode and waited about and hour and a half to see if it crashes and it didn't. So I booted it regularly and tried running malwarebytes to see if there was a virus and halfway through the scan it crashed. So I tried again while running task manager on the side and saw the CPU was pretty high so I took the HDD and put it in my old laptop which had no problems and turned it on and it crashed still so I'm pretty sure its a virus of some sort what should I do?
