I installed on my mums pc an HD 4850 to be able to play Bad Company 2 but ever since i m going crazy.No matter what game i run monitor flickers like i have 100 mobile phones next to it and looses signal, when i shut the game everything goes back to normal.There is no overclock and the temperature is just fine @47 Celsius since i installed an aftermarket cooler on it (http://www.scythe-usa.com/product/vga/002/scvms1000_detail.html) I tried almost everything re-sited the card on mb, clean installed new drivers, even reinstalled the aftermarket cooler but same thing...i m loosing my mind here!please help. Here is how the problem looks like. http://www.youtube.com/watch?v=qQaLHOnrmMk Thanks for reading
