If you have an open slot on your motherboard, try moving the card to it. May not make any difference but way back when (W95 and ISA cards) I added a card that didn't like the first slot it was in, had all sorts of miscellaneous problems, call the manufacturer's tech line, after adjusting all kinds of settings to no avail, one tech suggested trying a different slot. Cured the problems I had been having. Made no sense to me but it worked. Might be worth a try.
