I have to say that my new PC, that I built for gaming just one year ago, is doing the same thing. It didn’t start doing this until the latest patch. As an IT professional, I’ve checked what I can on my PC (temperature, etc.) Since my PC is only a year old and built for gaming, and it doesn’t crash on anything else but this (it plays RuneScape and SWTOR and Rift with no issues), I can’t help but feel that the issue is with the game. Possibly the newest patch caused some driver conflicts. I don’t know. But so many people seem to be having the exact same issue, so unless everyone is running an older PC with only a gig of RAM or something, I’m not sure the issue is collectively all of our PCs.
