On this machine I've found the vid drivers from the maker are the ones that work.
I've tried some of the newer nvidia one-size-fits-all drivers and noticed some quirks.
Sometimes when you bring in a new driver and try to put it over the top of an old driver things get twisted.
Sooo, d/l the new driver to some temp area.
Use add/remove and remove the old driver.
Reboot and let windows get itself sorted.
Navigate to the temp area and run the installer for the new driver.
I should have left well enough alone!! I downloaded drivers from Nvidia.com for the NVidia FX 5200 and installed them.
After that the PC (XP) would start to load and then lock up ( it would stop on the loading bar). I had to go to setup (F2) and change to "onboard" video to get windows to load. What happened? I tried reinstalling again but no luck.
When I go to Ctrl panel - System - device manager, it shows it as being there with no problems??
HELPPPP!!! It's "driving" me nuts.
