I have now experienced a complete game lock up at least a dozen times. While the client is locked up the mouse is still responsive, the keyboard responds slowly (e.g. ctrl-alt-delete takes a while before it brings me back into windows). The audio plays for a few seconds and then loops over and over a one second interval.

Sometimes the lock-up results in a "You have been disconnected" dialog after about 30 seconds. I can click OK on the dialog and reenter the game from the character selection screen. But occasionally it will cause the client to close completely. I have lost quest progression progress twice now. I am getting really good at killing the skeleton king.

I updated my graphics card drivers, Windows is up to date, I run in admin mode. The problem still persists.

Graphics Card: NVIDIA GeForce GTX 470
OS: 64 Bit Windows 7
Ram: 4 GB
CPU: Dual Core 1.8 GHz
