Installing Drivers

I cannot seem to get my system to install drivers for my Nvidia ti4200 Video card. I had a problem, reinstalled windows XP Home. Everything loaded fine but these drivers. I have a yellow question mark next to “other devices” in the device manager.When I went to the wizard, it started the install then stopped, so I reset the machine, it went to scan disk and completed it, then the screen came up garbled with verticle lines through it. SO, I went to safe mode screen, and I highlighted “last configuration that worked and it came on fine, but the drivers are still missing. Need some help here thanks,
