Sound issues with Windows 7 64-bit and MSI K8NGM2

Howdy,

I've spent a hell of a long time trying to get my living room / multimedia computer working properly, and am continuing to encounter problems with getting the system stable while doing 5.1 audio.

The system:
Windows 7 64-bit
MSI K8NGM2 micro-ATX socket 939 motherboard
AMD Athlon 64 x2 4400+
3 x 1 GB Kingston DDR RAM
XFX Radeon HD 4670
PSU Corsair 400watt
SATA Western Digital 1 TB Caviar Blue
SATA DVD/RW

At this point, I just want to be able to do 5.1 surround sound upconvertion of stereo sound (music). I tried to use my audigy 2 ZS platinum pro card in either PCI slot (in large part due to having a optical input), but kept encountering bluescreens. I think it was an issue of IRQ assignment, but I couldn't figure out how to fix it via the BIOS options. Fixing this would be the ideal solution, but it's pretty damn technical, would probably involve registry editing, and I'm skeptical anyone with more know-how on this would be willing to take the time to walk me through it. I would be tickled to be proven wrong.

DVD playback is working fine with 5.1 when I use the onboard realtek ALC880, but there is a LOT of noise on the rear channels. I can't figure out how to get upconvertion of stereo (nor do I know if it's even possible) to 5.1 with the Realtek though. I can't locate nor install a realtek audio control manager that would (hopefully) allow for upconvertion. So far, the system hasn't bluescreened since using the onboard audio and removing the Audigy card.

So... I seem stuck with either having my lesser onboard sound work okay for movies, but won't be able to take proper advantage of my sound system for music playback... or having the Audigy 2 ZS Platinum Plus in and having all the audio playback functions I need/want, but having massive system instability / blue screens as a result.

Thoughts / suggestions welcome. (No, I can't afford to dump money in this old system. I have spare audigy 1 and 2 cards laying around... I'd really like to use one of them, but I'm pretty sure I'm hitting IRQ issues.)
