i have a gigabyte H77M-D3H motherboard with an i5 3470 processor and 8 gb ram. i have updated my bios from f6 to f9. i brought an asus nvidia geforce gtx 660 ti dc2. the driver version was 306.87. when i try to play any games(medal of honor warfighter, nfs mostwanted 2012, farcry 3,call of duty black ops 2) each of this game crashes. it is showing in the task manager but i m being thrown to desktop with the game minimizing to taskbar. i m running windows 7 64bit sp1. i also updated the bios for the asus geforce gtx 660 ti but it still crashes. Gigabyte H77M-D3H supports nvidia card or only amd radeon. Thankyou.
