Hi Ajm786,
You shouldn't bump posts since its against our
Forum Rules especially so soon after creating the thread, People will reply when they have the time.
Have you uninstalled your NVidia drivers before installing the new versions (175.16 latest) this includes Rivatuner too and have you launched Riva with Administrative Permissions?
Can you post a screenshot of GPUZ so we have some information on the graphics hardware/bios your using? I believe you have a EVGA 8800GTS if Im correct...
