So I recently bought the Sapphire HD 6750 and it will not work. It will load fine and be okay for like a min and then it randomly just start flickering like crazy. Ive upgrading my PSU because before I thought it would not work because my PSU wasnt strong enough. So this didnt work. For my mobo i have asus p5ql-pro and there is nothing wrong with it because I can still run my old GPU on it. So does anyone know if I have to update something or whatever to get the graphics card to work on my computer?
