My computer tends to have a full system crash (complete shut down, no warning, instant black screen, fans stop and then auto boot) when playing more demanding games like Bioshock Infinite, Far Cry 3, and so forth. Now, I've figured out that I could play these games if I used MSI Afterburner to underclock my GPU and increase the fan speed to 80% Although, this fix isn't working anymore, now it's just becoming more frequent crashes. Without underclock, game will crash a few minutes. With, it used to be able to stay until I shut the game down but not anymore. Also, I thought it may have been a dust issue since the problem did only begin to occur a few weeks after winter break when I installed Far Cry 3 after my computer had been off for 3 weeks during xmas. But I just used compressed air to clean it as much as I could, a good amount of dust came out and the problem still remains. Any help would be greatly appreciated, for I am now clueless on what to do. And yes, I have done my research as to why this is happening, browsed many forums.
