You know, guys. I was thinking about it, and it's probably an IRQ problem. See, I was checking out the IRQ assignments in my pc, and 1) They are all full (I think, I mean, they go up to 15) 2) The same IRQ that's for PCI bus steer (for the free PCI port, I think) is also the one used by the onboard. Correct me if I'm wrong, but this should be the source of my troubles? Right? It should cause the monitor to not get the signal? (Yes, I have tried uninstalling the onboard and did plug in the monitor to the new card). If I'm correct, I think when I turn the pc on (which has the video card and the onboard if I put it in), both the onboard and the new card are IRQing(or whatever verb IRQ converts to) the cpu, with the same one (3). That should cause that, right? Tell me if u know.
