Does anyone know of any reason the x700 pro and geforce 6600 gt agp wont work in my emachines t2085. I got a new power supply, a 400w dynex and a 350w antec and neither helped. the x700 worked for a day or two then wouldnt boot the 6600gt wouldnt boot ever. I have tried numerous cards and tried them on other systems and they work fine. thanks
