My new SINXP will not put out a video signal. The card that is ment to go in the system is a AIW 9700 Pro, but it would boot, but the monitor would not get a signal (tried two monitors, that work with other computers). I then swaped the AIW out for a old PCI voodoo card, still not video, the I tried my known to be working GeForce4 Ti4200, and still not video signal. I am not geting any beep codes at post or any thing. What in the world could be wrong?
