My suggestions would be to visit Intel's web site and download the latest version of the drivers. Since you have a P4, it's probably either the 82845 chipset or the 82865 chipset. It should be pretty clear if you look in Device Manager under system and see if you have a dozen 82845 or 82865 devices. After you download, install, and reboot, upgrade to DirectX 9. And if it still doesn't work, pray that your system has an AGP slot and go buy a new video card.
