I just got a new computer its an intel 233mhz mmx it has a s3 375 2meg video card 96megs sdram and a pure 3d I will be on the computer and ithe moniter will go black and there is nothing running in the computer but the fans I lose all video signal.I should also tell you that for some reason the video card is using IRQ 11 along with IRQ for PCI steering some thing I have never heard of.I have never had a video card use an IRQ.Is the video card bad and shutting down?Or what else could it be?
I also have a pure3d card in addition to my 2d windows card. After installing the Pure3d, i also had that happen to my computer. What you need to check is the wiring. Make sure you have the Pure3d card cable connected properly to your Video output slot and that there is no slack or missing pins.
