Remove the display driver using: Guru3D - Driver Sweeper

Then install the ATi drivers: ATI Radeon

I have test the memory with the "windows memory diagnostic tool" and normaly got in windows enviroment.I believe that memory is ok , i think that i should buy an nvidia card to solve my problem.

The best you can do is to test the card in another PC or get another one
