I am having a problem with the recently installed Ge Forces 5800 graphics card. While the physical installation went okay, and Windows XP appears to have installed it,it shows up as being there,there are some problem. When I turn on my PC the screen shows a message, "out of frequency" for about 30 seconds the starts up. Do I disable the original default card? Actually it was'nt a card as such, part of the motherboard I suspect. The CD that came with the graphics card will not install because it says it can't locate an adapter,huh? Lastly, at start up if I click the F8 key, I get a black screen and no chance to do my thing, i.e. delete index.dat files. I am NOT a techicnal person but I could sure use some HELP.

I have a big porblem here. When I install my new video-208 PCI video card (128 mb), my computer doesn't boot up ( well it does boot up but everything is black)
I have another PCI video card, but that came with this computer, and i t has the port to plug in my internet wire ( i have dial-up). It's called Sis 651 and it contains only 16 MB!!!!!.
Can you please tell me what my problem is????????

P.S. I'm not an total expert on this ground, so please in plain english
My computer has: 1.8 GHZ, 624 MB RAM
