Ok, I don't really need help on how to uninstall the 27.10 drivers, but I do need to know how to get rid of the registry patch that I downloaded to enable the "hidden features." Without the patch my system was running great, now it's locking up and freezing or just plain restarting, and it's happening at a regular basis. I'm running WinXP Pro, with a Geforce3 Ti200. Please some point me to the right place to delete this registry entry, or just give me another way to get rid of it. Like, if I unistall the 27.10 drivers, would it take the registry entry with it? Thanks for your help.

it might, but i'm not sure. try it and see

Also, I'm looking for version 21.83 of the detonator. Can anyone give me a link where I can find it? That has been the best driver for me, although before the reg patch, 27.10 was doing great. Also, if say I went to Hercules' website and downloaded their Geforce3 driver, would it work even though I don't have a Hercules card? Once again, thanks!

Nevermind, I just went to the Nvidia website and searched for older drivers and found it. I'm going to try and uninstall 27.10 and install 21.83 and see what happens. Any ideas are still welcomed. PLEASE! Especially on how to remove the reg patch. Thanks!

To remove the reg patch. Why don't you just open the reg patch in notepad, make a note of the registry line, open regedit and manually remove them?
