drivers nvidia gforce4 mx420 for xp

You can download the full driver package from Nvidia themselves.

Note: check with the company that made your card. They may be using 'unique' code in the driver or BIOS to improve performance. If the card mfg has drivers to download, use theirs first.

The Windows Update driver is going to be the WHQL version of Nvidia's driver, and may not work correctly for ALL video cards with Nvidia chips on them.

Other things to check:

Video card Mfg for a VIDEO BIOS update.

Motherboard mfg for both a BIOS update (for Nvidia compatability) and AGP mini-port driver updates.

you need to download the detonator drivers for win2k/xp from nvidia.com.
1) got to Download Drivers
2) select drivers for win2k/xp
3) on the left of the screen you will find the words detonator drivers. Click there.
4) go to the bottom of thescreen and click on the link for detonator 40 w2k/xp and you are on your way.
Make sure you dl the XP driver. It is version 40.72 for both. THis should solve your problem. Also if you have a via board you should download the latest 4in1 drivers,now known as Hyperion drivers. I had a hell of a time with my gf3 when I first got it and tried to run it on xp but the detonators really helped. good luck
