While my brother was playing a game (Starcraft II) the was a pop noise, the computer died and the house's fuse was blown, and he could smell smoke. What has happened, I'm guessing a problem with the PSU or motherboard? I can't believe this has happened after we bought a new PSU specifically to have a more trusty and well-reviewed corsair, this current build is driving me a bit nuts!
