Hi Joe,
This one is certainly a difficult one to debug. The first thing that I would suggest is upgrading your bios. Go to the manufacturers website and look for bios updates. Secondly try a different ISA slot. Sometimes the slot has failed and switching to another slot fixes the problems. Third, check that your jumpers are set corectlly and it agrees with your bios settings. I would also try the card out in another computer. If the same behavior is exhibited, it could be a problem with the board.
Hope this helps,
Best Regards,
