AGP Controller problem

Hi All,
I'm running Win98. The Graphics acceleration has not functioned
properly since a freeze-up while installing a program. (program was
uninstalled). Slider is on High in Device Manager, but pages load
slower than normal. Moving slider all the way off causes jerky
scrolling, so I know it's working on some level.

In Device Manager, Intel AGP Controller is enabled, but Driver details
button is greyed out, and it displays a message, The resources this
device is using do not match any of it's known configurations. Also
says, This Device is working properly, and no known conflicts. DXDIAG
and Everest report that AGP is disabled. This may cause performance
penalty. AGP aperture size is more than half of the system memory
size. This may cause performance penalty. In Everest, the Aperture
sixe is 64MB. I have 128MB installed. Adequate for my uses.

I have installed new Drivers for the S3Trio 3D Video Card, no change.
I tried removing the AGP Controller in Device Manager, and
reinstalling, no luck. I don't remember if it was in Safe Mode or
not, though. Any ideas what is causing the problem, and how to get
AGP to working properly again? Thanks in advance.
