No Output From Onboard VGA or PCI card VGA

I've been trying to fix a problem with a fairly old pc which is used by a school but I'm having a few problems. The original motherboard had completely had it, nothing I could do would work. I have aquired a new motherboard but I am getting no output from the onboard graphics or the additional PCI graphics card. It is not the monitor or monitor cable, those have been tested with another pc. The processor and RAM also work fine.

Does anybody have any idea what is wrong or what I can do. Any help will be very very very much appreciated!

Thanks

    If it's a SiS chipset based motherboard I'd say plan on getting a new one because when the onboard video on one of those dies the board is useless, no other vireo will work on it.

    I have seen a few chipsets by SiS that are wired in sych a way that the onboard video can be disabled with a motherboard jumper. And have had a bunch eat\devour\pretty much discharge way too fast, a CMOS battery. Then another.

    Agree as to junkiing board if a replacement can be gotten, or board RMA\exchanged for different model. I have also had no video after resetting CMOS, until both kinds of video were connected at once, and then I discovered someone had managed to get the "refresh first" video display type set to PCI and not AGP or vice versa and the board was trying to use the disconnected port to feed video. Can you hook one monitor to builtin and one monitor to a PCI card (both vidoe ports connected to monitors or a KVM switch to one monitor at once), see if either then display???

    Yes I'll try a monitor on each of the outputs, i'll have to have a look for a manual for the board to find out which jumpers are which. If this fails I can just get my money back so not a problem.

    Thanks for the help

    if the old motherboard had completely had it, is it at all possible that at the same time the old cpu had it as well? are you sure the machine is posting and the memory / cpu isn't the culprit here?

    The board doesnt work with a different cpu or dimm of memory so it has to be the motherboard
