biostar ta790gx128 mobo
Phenom x4 9950 cpu
Currently hd 4850 gpu but the new one is sapphire hd 6850

i bought a 6850 and it spun up to full speed and just sat there so i returned and got a new one. fan doesnt spin all the way now but still get no video. i updated bios. tried wiping all old drivers and even tried the molex adapter for power.
