Problem with 6800

[joe588]

Hi guys, I recently bought a geforce 6800 (not gt or ultra), and it dosnt work. It's the PCI-E version. When ever I install the drivers (doesnt matter which drivers I install - official, windows version etc) the computer crashes. Shortly after I get a blue screen message saying something like machine_check. Am I right in thinking that this card does not need an extra power cable plugged in? I can't find anywhere on it to plug it in....

I bought card off ebay so I dont have the manual or anything. My specs are...

3000+ venice 64,
GeForce 6800,
512mb Ram
Ati chipset RS480 motherboard (optronix)

Thanks alot, Joe

Does the motherboard have onboard graphics? If so then you might have to get into the bios and disable it if that's possible. I don't know anything about that board, but I guess you might have nVidia and ATI graphics drivers fighting with one another. Just a thought.
