I have got an old 8meg ATI XPERT@PLAY 98 AGP 2X video card, with which everything runs fine.
When I try to install my new GeForce 2 MX 400 my PC will not even boot up. I have tried various other cards like the Voodoo 4 which run on other PC's, none of which will run on mine.
Now I want to get this right. The computer will not boot at all, or the video display doesn't come up. I don't see any reason why a vid card would cause the entire computer not to at least start booting. Are you getting error beeps or anything?
