Assuming this is the same card:

I would first off set it to defaults.

If issues persist go into C: Program Files/NVIDIA corporation and delete then reinstall.

Its not overclocked anymore, hasn't been for awhile.

I had no Nvidia programs in my C: Program files. I had them in C: Nvidia. I deleted that folder. Went to install 191.07_desktop_win7_winvista_32bit_english_whql driver same old error saying its not compatible because I'm not using Win7 or Vista 32 bit. Also wouldn't work in compatibility mode "Vista SP2 32 bit"
Now the driver won't roll back, so my screen looks like poo at the momment.

I popped in my installation cd and got the files back and rolled back the driver but still no Nvidia control panel.

I went into the CD looking for the control panel files and I ran the setup, it failed it said:

The wizard was interrupted before it could be installed, I didn't cancel or anything

Setup failed to read the required display driver to run this setup in windows XP sp2 comaptible mode

Is there any other way to adjust hardware acceleration, maybe a different but compatible program?

The new 195 beta driver says "The Nvidia setup program could not find drivers that are compatible with your system. Setup will now exit"

SUCCESS!

I contacted BFG support. They informed me that I didn't need to unitall the old drivers first. Just download 191 driver and install like a normal program and it worked.

Thanks for your time Jephree,

Thanks for all the updates. Glad all is well.
