Wow, that is a fantastic guide!
I went through it step by step. The only thing I'm not really able to do is roll back video drivers - I'm using the current stable AMD drivers (from July, I believe).
I think I may have made some headway - I logged in, went into a character, stood around for a while (long enough to be AFK several times) and no crash. Yesterday I would crash out after several minutes even just standing still.
Unfortunately...that was as good as it got. I ran my toon over to a vendor, and as soon as I right-clicked, crash to desktop.
So now I guess I need to look at logs. Can you advise on which logs may be beneficial? Or should I just proceed on to calling EA support?
