Use XPpro/SP3 with M3N-HT motherboard with AMD 9950 cpu and GTX280 video, I have the motherboard nVidia DVD but when I install the chipset drivers and re-boot the computer seems to open normally, but shows no video. I have also tried with XPpro/SP2 with the same result and I have even tried the nVidia drivers on their site. I cannot get advice from nVidia so please advise.
