Help! Just put together a new box with dfi motherboard (ad73) with athlon xp1800, 256meg ram, nic card, and one matrox g450. I let the xp disc partion, format, and install OS. Then I download and install latest VIA 4in1 drivers. At this point system seems to work ok. Then I install the matrox drivers (tried the CD, the latest download, the beta download, and the "unified" download). All fail in the same way. Upon restart after driver is installed windows opens with either a locked welcome screen or a matrox dialog box. In the later case, just moving the mouse corrupts the screen, and crashes windows. I've spent over 2 hours on the phone with matrox. They don't know at this point. Any ideas?
