I reinstalled AVG and my computer blue-screened again; I received a out of memory error. I had only 1GB of RAM (I wanted to see if I could get the computer running before adding additional hardware) so I suspect I was very borderline on resources.
At any rate, the computer rebooted this time and all the AVG options were loaded, save for one. During the AVG installation my Firefox became corrupted when the computer crashed. I was able to reinstall Firefox and the remaining AVG program but the computer was running painfully slow.
I added 2GB of RAM (for a total of 3GB) and my computer is now running stable (about a week now without incident). AVG is a bit of a resource hog though as sometimes just launching Firefox or a Word document takes several minutes (compared to a few seconds prior to installing AVG). It's not unbearable and I guess that is to be expected with antivirus software.
