I've been running 2 dual Matrox 450 PCI cards, 16M and 32M cards. My computer restart automatically a few times during the day. I've gone into Win 2000 and turn off the automatic restart but it just ends up freezing up in a blue screen. I've reformated the hard drive half a dozen times. I've downloaded the updated drivers at the Matrox website. I can't figure out what the problem is. Could it be the NEC screens? or the 16M and 32M are incompatible. 2 NEC 18" 1850 E Flatscreen 2 Sony 17 Trinitrons P4 1.6 512 Cache P4S-333 ASUS 512 DDR Ram 20 g harddrive Any help would be greatly appreciated. I'm just about to throw the computer out the window.
