Just a heads up. Was playing a game when it crashed and Reliability History showed the culprit was a forced graphics driver update. Which is unusual because I last updated around a month ago, so not that long ago. Searching for news about this brought up mentions from others about it too, and another OcUK forum member had issues with his SLI and custom BIOS setup after the same forced update. So if graphics issues are experienced, seeing if they coincide with a forced graphics driver udpate (it won't tell you it happened unless you check for it) is one thing to investigate.
