Hello everyone this my first time posting an issue. I have a video card Geforce FX5500 (Just purchased on 8/17/07) installed into my machine which is connected to my TV. I disabled the internal video card also hit F1 (BIOS) switch setting to PCI. Everything was in proper working order. Until, I answered several questions during setup in my windows media center and reboot. The windows xp display is clear with the processing meter. When this is over, the display is know distorted with a bunch of line running horizontally across the screen. Does anyone have a quick solution to the above? Thanks
