It sounds like an IRQ conflict. As a quickie, make sure it isn't in the
first PCI slot; that shares with the AGP port. And if your motherboard has
5 PCI slots, 4 and 5 share so don't put it in one of those along with
another card. (PCI is a 4 slot system and extra slots are 'expanded' from
one of the existing slots).
Then you have the problem of on-board devices which, although 'on the
board', are equivalent to having a 'card' plugged in. The problem being how
to figure out which slot they're 'expanded' from (I.E. sharing with).
You may need to specifically assign an IRQ (perhaps 2, depending on how it
works) to the PCI slot with that card so they're exclusive to it.
Also, make sure your BIOS is set to "O.S. not PNP." It sounds backwards,
since Windows supports PNP, but turning that off forces the BIOS to assign
IRQs at boot rather than leaving them indeterminate for the O.S. to handle
later (the O.S. can always change them any time it feels like regardless of
that PNP setting).
