I've got the video card mentioned, and we had tv out working fine. Then we moved our setup around a bit, both PC and the TV, and now we no longer get an image on the TV. The settings had changed somehow, and after setting them back. we get a "moving image" with blue being the only color. We've gone through and checked the settings, everything appears correct, we've made sure all the cables are attached properly.

Thanks for your help.
