Hello people, I recently bought this card...after installing it on my mobo my pc started without any problem but after installing the drivers when I restarted it, windows doesn't boot, even I am unable to enter bios setting,
The only thing which happens is initial screen comes where my hard disk , DVD rom, ram is displayed and other options to enter bios are shown then either it restarts again and again or freezes with a black screen

Someone plz help

Core2duo E7500 2.93ghz
G41 combo motherboard
Corsair xms3 4gb ddr3 ram
Psu corsair vs550
