I bought a new mother board IntelDG41RQ. I had a old graphics card which is XFX7200GS. But currently I cant use this card. When I insert this in the PCI slot on my board without NVIDIA driver it works properly, but whnever I install the driver on my system, it strts mal functioning, like my display are blinking again & again. I cant understand the problem. Please any one solve my problem.
