When I run Diablo II, Homeworld, or Need for Speed - High Stakes, my machine randomly locks up completely. I've noticed that when I run dxdiag.exe, it says that my video and sound card drivers are not certified, yet I have the latest drivers for each. Are these 2 problems related? I talked to a Sound Blaster tech and he said make sure the sound card is not in pci slots 1, 4, or 5 (which it's not, it's in slot 3 with a NIC in slot 2 (all others are empty). I'm running a T-bird 850, 128 mb RAM, Voodoo 4500, SB Live value, Maxtor 13.6 gb UDMA 66, and a SOYO K7VTA-B motherboard. Any suggestions for the lockup or direct x issue? Thanx in advance for your help.
