Just got my PC back from the techs, was running fine, and played a few times online. I upgraded my RAM to 512 and less than 75% of my HD is full.
Now, when I try to load the game the PC locks up and goes to the blue screen. Never had this happen before, and the PC has all sorts of recently updated firewall, adwarer, and virus protection programs on it.
One day everything related to AH works, and the next, I can't even load the game.
I'll provide additional specs if you think you need them.
