I have the same card Hamrah - you're obviously a bit of a games player on the side as there is no other use for this bit of kit !
Have you tried hitting F8 on start-up (or is it F9 ?) and selecting to boot-up in protected mode ? This will force a default VGA driver which should work with any video card.
I doubt your card is incorrectly seated as you would not see any of the BIOS start-up info (in fact - no video at all) and it does sound like a DMA/IRQ conflict, as suggested previously, which should be removed by booting in protected mode.
Once there, fire up the control panel and remove any non-essential devices from your configuration.
As win95/98 automatically configures dma/irq settings, the only explanation I can come up with is that you have manually assigned some resources to some other kit you have, or your card is defective.
Cheers
