so i bought a 9800gt, ddr3 card, and when i put it in the comp all i get is a black screen, ive tried using DVI cable, and vga with an adaptor as its only dvi on the card (dual dvi). so would my mobo have to be compatable to support dd3, or what. its s PCI-E card, my mobo isnt that old. thanks.

hmm got it working, but i think its fked cus it crashes in games

check that all your bios settings are correct for the video card.

what settings?

normally run dual screens but ive dropped back to 1 and seems to be working. think its driver issue, so wondering if i could use an older nvidia driver?

why use an older one? go the the nvidia website and upgrade to the latest vs
