Hello, I was given a Dell Dimension 4100 (please don't laugh; I realize it's obsolete. The original purchaser bought a new Dell.) I'd like to upgrade the video card but it doesn't want to work correctly with anything but the original GeForce 2 MX (32MB) card. I've tried a GeForce 3 Ti200, a GeForce 4 Ti4200, even a GeForce 2 MX 400 (64MB), all with the same results: The machine boots in 16 colors at 640x480 resolution (which looks terrible) and if I make any changes it won't boot at all (it completes POST and sits there).
The machine has WinME and I've installed the last nVidia driver that supported 98/ME (81.98).
Found and downloaded DriveSweeper and burned it to a CD-R to take to the Dell. Promptly got an error message - some DLL not found - so couldn't use it.
I then spent a couple hours going through the same procedure; change cards, re-boot, and no-go. Stir and repeat. The closest to success was a GeForce 256 card with 64MB, but it wouldn't work once I changed the color depth.
I finally got the original card working again with nVidia 81.98 drivers. The GeForce 2 MX actually looks good, but I'm not satisfied with it - especially when I have an assortment of better cards (with more vRAM) sitting around.
Discovered one detail: The card I thought was a GeForce 2 MX400 is actually a GeForce 4 MX400, which could make a small difference, I suppose.
I know some of the components (like the power supply) are not industry standard, thus I have to wonder if Dell did something in the software/drivers to make it so that only Dell tech support can change the graphics card? Seems far-fetched, but it's possible...
