I recently installed a Pc-100 100mhz bus motherboard, and a Cryrix 6x86MX 333 cpu. Whenever I'm playing Startrek Academy now, the video presentation that exisit between missions goes black for the lenght of time it takes to get the mission parameters. Then if you tap the space bar the screeen pops back as if all is normal. While the screen is black there's no sound but a really faint image in the backgroud of the video seg being played. When I were using a 66mhz bus motherboard and a 233 cyrix cpu eveything worked fine. Does anyone have any suggestions or has anyone seen this before?
