First of all, here are the computer specs:
N82E16813131665
N82E16814121423
N82E16815158113
N82E16817341018
N82E16819115211
N82E16820145222
N82E16822152185
N82E16827151233
N82E16832116989
N82E16811119233

(Don't crack me on the 32 bit OS with 6 gigs of RAM, that was what was specified)

The StarTech RS232 PCIe card refuses to be recognized by either the motherboard or the OS (in device manager when I try to update the driver an error message pops up stating that this driver isn't compatible with the OS). With the exception of the speed of the RAM and the optical drive I built the same exact system about a month ago and it worked flawlessly. I have ordered another card (the first MB for this build died and I had it replaced) so I am hoping that will remedy this situation.
I have one question about the BIOS settings. Under the Advanced tab, PCIPnP it has Plug and Play O\S defaulted to NO. Could this possibly be the culprit?

Leave PCIPnP at No. Is it showing up in Device manager? If so, that means the board and OS is detecting it. Is the driver your trying to install for Windows 7?

On the other build it showed up as COM 3 and 4 and also as Multiport UART adapter (2 entries in Device Manager). On this build it was showing as 2 separate Communications ports with no entry for Multiport UART adapter.

PEX2S952 here is a direct link to the manufacturers webpage concerning this card.

Dont know if you need two Com/Serial ports, but most boards come with com port pin already on them. Know that one has one, not sure about two. But you can just use one of these.

On the card in question, the second port is connected to the card by a ribbon wire and connector. I plugged this ribbon wire into the com port pin that you mentioned but the device that is connected to this port won't show up in the software that utilizes it. I tried changing the IRQ in the BIOS for this port but none of the choices worked.
