First stop would be to check on the game to make sure your PC meets the requirements to run game correctly . Have you tried running game at a lower setting ? also check the graphics card driver , and PLEASE , DONT BOOT OFF with power switch unless absolute LAST resort . Ctrl, alt delete and shut down , Windows will get very upset with you , and start sulking !
