I have an older machine (1.5 ghz) with a 128mg ELSA Gladiac Ultra card. I was trying to get updated drivers because the latest patch of WoW crashed. Found out I hadn't updated my drivers since August 2005, but it had been working fine. So I got the latest drivers, 84.21 I guess. I foolishly followed NVidia's suggestions for installing drivers and uninstalled my current drivers.
After the NVidia Setup process copies the files, it launches an installer, which pops up an error message saying something like "Cannot find drivers for this hardware" or vice versa.
So I went back to the install disk that came with the graphics card and installed those, just so I could have a modern display again, instead of the 64 color, 480 size screen that resulted from having no drivers at all.
I went backwards in the driver archives and tried installing several earlier driver versions, and always got the same error from the NVidia installer.
I tried the download from Elsa and had exactly the same problem. The NVidia Install reports this bug : "The NVidia setup program could not locate any drivers that are compatible with your current hardware."
This seems like there is something more basic that is wrong, since I am getting this error when I try to install any NVidia drivers at all. But I have no idea.
"the nvida setup program could not locate any drivers that are compatible with your current hardware"
But I just found the solution and I'll write it up in hopes that it may help someone.
Make sure your new video card is not inserted
Then, load up and Look at your hardware profiles and locate your current VGA video device and DISABLE it
Then power down your computer
Unplug your monitor from the motherboards onboard video port
Insert your new video card and plug the monitor(s) in
Boot the computer
I had to restart 3 times because the video wasn't comming up on the new video card then on the 4th time restarting the computer, viola, both monitors came on from the new video card.
Boot into windows and load the drivers from the CD or from the web and they should load just fine without saying "the nvida setup program could not locate any drivers that are compatible with your current hardware"
The problem was that it couldn't load the new drivers because the computer was still using the old onboard video card.
