I heard from another site to fix this problem what you need to do is change the ffx86.dll file to ffx86.bak in the MOHAA main directory. I've heard this fix works for demos and I've also heard it works for the full version. I haven't tried this yet but I am experiencing the same problems. System crashing and rebooting me every 2-5 minutes of online or sp play. I haven't tried the soundcard fix either yet but I've spent a good 15-20 hours trying to troubleshoot this problem.
My specs:
Gigabyte GA7DXR motherboard
AMD Athlon 1.2ghz processor
512mb DDR RAM
Asus GeForce2 V7100 MX400 (32mb)
Soundblaster Live Value

I'll try this once I get home but if someone else is at home trying to fix right now and has lost almost all hope as I have, try renaming that file.

Good luck.
