Thanks for taking the time to do such a thorough response! I had uninstalled Mcaffee when I first bought it, and have been using the Microsoft Security Essentials since then. Apparently it must not have completely uninstalled? So I downloaded the uninstall tool and ran it. It appears that driver is no longer there.
I then went and tried to update all of the drivers you listed. All are now newer drivers (never really sure if I have the latest, but at least they are newer), except for the ATK64AMD.sys. I installed all of the driver files available related to ATK for this system from the Asus site. That one is still the 5/12/09 date.
After I completed these updates, I got another BSOD. I was going to rerun the utility to post the info about it, but I noticed that there are no dump files newer than 8/15. I had two crashes last night, and one tonight (8/29 and 8/30). So I'm not sure if somehow the dump files have been turned off? Any ideas would be appreciated.
