Hi I just installed my AGP geforce 6200 512mb card and I cannot get it to work. I cleared all my old ATI drivers, and installed the new card. Windows detected it and installed the driver files then prompted for reboot all as expected. During the black and white boot screen the video is distorted but readable with light and dark lines about 4mm thick running vertically on the screen. The windows logo screen has thin white lines vertically, but then when windows actually starts I lose all video output and the screen goes blank my monitor says no input signal. I can reboot into safe mode and the vertical lines are still on the screen but windows loads. If I change my display setting in safe mode to 16-bit color the lines go away. When I check settings in CMOS it says AGP 8x and I am unable to change it. my old vid card would let me change it.
I have uninstalled and reinstalled drivers a couple times. I d/l the newest driver from nvidia website with no luck. I have tried 2 different monitors: new Hanns-g 22"LCD an an old 17" mitsubishi CRT both with the same results. I removed all nvidia drivers I put my old ATI radeon 9000 card back in and installed the drivers for that until I can figure this out.
Also I was reading my mobo manual and it says I need a 1.5v AGP card but there is no volt spec on my vid card.
I am using a Asus A7v8x-x mobo with a via chipset, AMD athlon xp 2400 2.0 processor, 1GB RAM, 450w power supply. running Windows XP ver. 2002 with SP2.
Please help!
thank you
