I tired today to "downgrade" from currently posted Nvidia detonator driver to the ver 23.11 (at suggestion of Jedi Knight 2 tech help forum).
After doing this I get an error message after Windows 98 boot:
Error in NvQtwk
Missing entry: Nv CpIDaemon"
I have tried loading VGA Drivers, then coming back to 23.11, but I now get this message with any driver I load.
You didn't say which motherboard you have but if you have a Via chipset the drivers, chipset and video, can get really messed up. The most reliable fix I have found is a clean install of the Via 4-in-1 drivers (uninstall then reinstall), clean install of nVidia drivers (use Detonator Destroyer), and a clean install of DirectX 8. For the last I use DirectX Uninstaller but it's no longer available and only worked for Windows 9x. I have a new utility called DirectX Eradicator but I haven't tested it yet. It claims to work for all Windows except XP.
Anyway, all three of the above steps together fix a host problems. However, if everything is working right now don't mess with it. Just keep the above in mind for any future problems.
