Okay, so, my PC will occasionally crash after exiting a game. I'm pretty sure I have all my drivers installed and up to date. This can happen on any game, it's very strange. For example, it has crashed on Assassins Creed 4 before, but today when I played it, it did not crash. I've tried to read up on a lot of articles for some help, often people say something like a RAM issue, but I don't understand how it would only sometimes crash? I've ran a memory diagnostic tools test and I had no problems, but I'm not sure how accurate or how much the test goes in to depth is. Any help would be appreciated, thank-you.
