Hoping I can get some help from the forums here... I recently bought an XFX 6800XT (http://www.newegg.com/product/product.asp?item=N82E16814150163) and tried to install it in my machine. When I try to boot the machine, it POSTs, but the display goes blank when it tries to load Windows. If I try Safe Mode and watch the list of drivers, it always blanks out after loading nv_agp.sys. I've RMAed the card for a replacement and had the same problem with both cards, so I'm wondering if the card is just not compatible with my motherboard. The motherboard is an Epox nForce3 board (http://www.epox.com/USA/product.asp?id=EP-8KDA3J). Any help/ideas would be greatly appreciated. Thanks!
