IRQ recource conflict. (Code 12)

My sound card (Creative Audigy 2 ZS, and Creative Game Port) is displaying this status in Device Manager:

"This device cannot find enough free resources that it can use. (Code 12)"

If you want to use this device, you will need to disable one of the other devices on this system."
--------------------------------------------------
During boot I get this message:

ERROR
Recourse Conflict - PCI in slot 03
Bus:0A, Device:04, Function:01 was unable to run due to memory constraints
(F1) to resume (F2) to setup
--------------------------------------------------
It started when I installed an eSATA card in the computer then pulled it out. I have tried putting the card back in but I get the same problem. What do I do to fix this?
