I recently tried installing a better video card in my computer, but have run
into serious problems. To give you a better idea of my situation, allow me
to describe my current system specs:

MSI 394TPro Motherboard
Celeron 1.1Ghz CPU
256Mb RAM
Windows 98 SE
Current Video Card : Geforce 2 MX440 32Mb (AGP)

This card has always worked well, allowing high refresh rates (100Hz) and
great game performance. But it's a bit outdated, so I borrowed an ATI Radeon
7000 from a friend to try out. Once installed, the results were poor at
best; it wouldn't allow a refresh rate higher than 60Hz, and game
performance was TERRIBLE - worse than the old card! I installed all the
proper drivers so I don't think that's the problem.
I've put the old card back in for now (for my eyes sake!), any ideas on
how to get the new one working? Or is it just not compatible with this
machine?
Thanks for any advice.
