Asus Crosshair III Motherboard AM3

I previously had an AM2 system with an Asus M2N32-SLI. I put the new system in and tried using it without reinstalling Win7. It booted fine, and everything seemed normal. I ran Dragon Age for about 10 minutes and it crashed to desktop with a C00005 exception. I decided to play it safe and reinstall Win7 so that it could meet the new chipset during its install. The installation went fine. Now, however, I get C00005 errors in Opera and some other programs, so I know that the error wasn't exclusive to Dragon Age.
I ran the Windows Memory Diagnostic tool and it turned up no errors.
I ran chkdsk and it didn't find anything wrong.
I ran Prime95 but the threads quit after an error - something about turning up a 5 when it expected a 4.
There were some other strange occurances:
Windows became convinced that it wasn't a genuine copy (probably because I'd changed the motherboard - had to register by phone - and then reinstalled in the same evening), but a restart later and it showed as "activated".
Some updates were downloaded, so I restarted. The system booted up and told me that changes were being made to my system and that it was 35% done, then it suddenly restarted and did this twice before it went through to the normal desktop.
I downloaded sound drivers from the Asus site and I'm running the newest Catalyst drivers. The system seems to run just fine about 70% of the time but the error will crop up eventually.
I'm at a loss because it seems like the problem could be anything. It's almost 4am here and I've been at it since 10pm. Any help is most appreciated!
