Slow redraws and overall speed after Radeon 9600 install

[fatejudger]

I just swapped out my FX 5200 in my Dell 4600 for a Radeon 9600 video card in order to support my new Dell 24 inch monitor's native resolution (1920x1200). After installing the drivers for the new card and rebooting, my computer runs horribly slow. Windows take seconds to redraw and loading a small application like Firefox causes the computer to lock up, presumably from low amounts of RAM. I'm not quite sure what to do next so any feedback would be apriciated. Thanks.

Computer Specs:

Dell 4600
Pentium 4 - 2.4 Ghz
256 MB RAM
30 Gig HD
Radeon 9600

If any more info is required, just let me know. I'd have posted my hardware model numbers, but I'm away from my computer right now.

That sounds more like thermal throttling than driver conflicts to me. Of course, in these days of super cheap RAM, your "256" looks puny, but it's not that -- somehow you've disturbed that system's cooling ability.

Yeah, my initial thought when seeing this is that there was a problem with the cooling. I had a friend recently that told me of a problem like this and I told him that it might be something with cooling, not sure how it turned out though, I guess I should follow up...

I would be inclined to agree with the hypothesis above, but it was slow as soon as I rebooted. Wouldn't a heating problem show up after several minutes of use instead of immediately?

By the way, if it is a heating problem, should I be looking at the heatsink on the card itself or making sure that the computer fans are in good working order?

Start->Run->dxdiag - under the Display tab, are DirectDraw Acceleration, Direct3D Acceleration, and AGP Texture Acceleration all enabled? If not, you may need to use DriverCleaner to clean out the old nVidia driver files.
