This is quite a dilemma which is driving me crazy. I wanted to install a agp Creative Tnt card on my friends computer who is currently using a STB riva128. Thus, I properly took out his video card and put mine in. Everything was fine until it came to installing the drivers. I downloaded det 2 5.22 nvidia drivers, 6.31 det3 drivers, and the creative 6.34 drivers and tried installing them. All of them installed fine but the darn thing won't let me change resolutions! His display is always set to 16colors 640x480 :(. When I check in device manager, the Nvidia TNT always has a yellow exclamation point and it says its installed but not properly. When I click on driver details, it says VDD.vxd not found. I guess this is the problem but I dont know how to fix it. The crazy thing is that I've installed this video card on his computer b4 and it worked fine. Thus, I thought I would just reinstall his old video card. Now his old video card which was working perfectly fine 30 mins b4 wont change resolutions as well. Thus, things were really bad now. So, I then decided to reformat his computer and start fresh with windows 98SE, hoping it would solve everything. Well, it didn't. The drivers would always install but when it came time to changing resolutions, it would always just stay at 16 colors at 640x480. I've changed/upgraded video cards many times and reformatted quite a lot and never came across this problem. Since both his video card and my tnt card now can't change resolutions, I'm thinking the Agp slot in his 440LX motherboard might be permanently damaged somehow. Could this be it? I sure hope not though, as I've tried everything I can think of and consider myself pretty experienced with this kind of stuff. When booting up, I notice that his video card has an IRQ of NA. Is this right? Maybe thats the problem but the only things he has in his computer is an ISA SB AWE64, Zoom external modem, Toshiba CDROM, and 6.4gig hd. Does IRQ's have anything to do with this? What could be wrong? I am open to any suggestions and would really like to fix my friends computer. Thanks.

Since I can't think of anything, the next thing I will try to do is install windows 2000 on his computer, this a good idea?

I had this same problems a while back. The "slider" wouldn't allow me to adjust the resolution to anything higher than 640x480 turns out it was because my monitor was set to unknown. When I updated my monitor to Default Plug and Play Monitor everything worked fine. If your monitor is in the list of recognized monitors just select it.
Hope this helps.

The TNT card MUST have an IRQ assigned, or it will have exactly the symptoms you describe. Drove me nuts the first time I put one in. There should be an "assign IRQ for VGA card" or something like that in the bios.
