I have a DG965OT mother board and everything was working OK. Upgraded to Win 7 and now my NVIDIA 8600 GT display card now shows Code 43 in the device manager. NVIDIA support can only provide new drivers but can't fix my problem. I upgraded all my Intel chipset drivers. Last thing they asked me to do was to upgrade my DG965OTBIOS. Intel has no Win 7 bios upgrade. What can I do to get rid of the Code 43 on my display card? All my drivers except the bios are up to date. Only odd thihg is that when I run Driver Cleaner I do see an ATI display but when I check it to clean it out - nothing happens and it will not get rid of it. I searched my programs an I have no ATI programs installed. I do not know why Intel is not providing Win 7 update to my 2 year old motherboard BIOS.
