Just got my new Dell inspiron with the Nvidia GeForce 650m. i downloaded black ops 2 and was running the graphics all the way up and everything was fine. then suddenly when i tried to open the game the next day my fps went down to 4 at the start up screen of the game. then it blacked out and started flashing the desktop. so i turned off my computer and now black ops 2 is still at 7 fps. WTF HAPPENED
