Hi, so recently my computer has been restarting, like everything turns off instantaneously then boots back up . This has never happened before and was wondering if someone could point me in the right direction. It happened twice last night and two times today and in both cases it happened when I had a lot of browser tabs open (doing research for a paper), could this issue maybe be related to the RAM? I also go into a game and played for over an hour to see what would happen and it didn't restart and I have also my computer on for hours with nothing open and it didn't shutdown/restart, only seemed to happen when I have a lot of tabs open in firefox. When playing the game my temps never got about 59c and I sit idle around 39c. Any help would be appreciated, thank you.
