You might want to print this out for reference:

1. Open the add/remove programs section and remove any 3DFX items.
2. Open display properties and go to the settings tab/advanced button/adapter tab/change button/display a list/show all hardware/standard display types/Standard Display Adapter (VGA)
3. Hit next and say YES to the warning that pops up.
4. Hit next-finish-apply-close and restart when prompted.

This finishes the first part. Next we need to run regedit when the system comes back up and remove ANY references to 3DFX, Glide, and VooDoo. To do this do the following:

1. Open regedit by going: Start/run and type 'regedit' in the open box (no drive letters)
2. In regedit, open the 'HKEY_LOCAL_MACHINE/Software' folder and delete the '3DFX interactive' folder.
3. Then open the 'HKEY_CURRENT_USER/Software' folder and if you see a '3DFX interactive' folder, delete this one as well.
4. Then click on EDIT from the menu bar at the top of the registry editor and click on 'Find'
5. Now, type in '3DFX' and hit 'Find Next'.
6. When it stop searching the registry hit the Delete key and say yes when it asks you if you are sure.
7. Then hit F3 to do a find next.
8. It is important that you keep repeating this pattern each time it stops (Delete, Yes, F3). Delete every thing it stops on, no matter what it is. However, do not delete anything but the first thing it stops on when it halts its search or you could delete too much. Let the registry editor search for each item you want to delete and this should prevent major problems.
9. When regedit says: 'Finished searching through the registry', close it down and open it back up and repeat steps 4 through 8.

Reg edit will not find everything on the first try so you will have to do steps 4-9 several times. Repeat Steps 4 through 9 for the words 'Glide' and 'Voodoo' as well.
