Hello, everyone. I'm having an odd issue. My computer will randomly restart at ANY time. When it comes back up, it will show the screen that says "Windows did not shut down properly (blah blah blah)." It seems to happen most frequently, when I'm streaming an online video. I want to say that it's mostly youtube, but that's probably because those are the videos that stream the most. It will also happen a lot, almost every time, while playing Magic the Gathering Online. These are not the only times that it happens, though. I have no problem playing more demanding games such as Diablo III, World of Warcraft, Starcraft 2, Guild Wars 2, etc. In fact, it almost never happens while I'm playing these games, but it has happened. I also have no problem watching a video stored on my computer. Again, almost never restarts this way, but it has happened. TLDR: Restarts any time. Restarts most frequently during online video streaming & MTGO. Restarts rarely while playing more demanding games. I've checked the temperature of both the CPU & GPU using a program called RealTemp. That seems to be just fine. I've opened up the case & cleaned all the components & that also had no effect. I'm really at a loss for what could be causing this. Any help you guys can provide would be greatly appreciated.
