I start up computer and no display. I repeat the start up 7 or 8 more times this time I get a display. When I install a program and reboot the computer I loose the display and have to keep restarting the computer. I have the ASUS TI 4200 8X AGP Card. The driver cd will not install. So is this a defective AGP card or a defective motherboard? I have the ASUS A7N8X Deluxe. I can install another hard drive and my old video card to see if that works.
