Screen Freezes

[Widem]

I have been experiencing times where my screen just completely freezes. I can still hear actions going on around me, but it forces me to restart the client.

I have researched the issue and some of the suggested fixes which do not work are:

Shift+Enter to move in and out of windowed mode. (This causes an error which does crash the program.)
Adjusting clipping planes. (Crashes Continue)

I know many other people have verified this happens to them with varying degrees of frequency.

Is this something I will just have to live with or is this a known issue which I just can't seem to find how to resolve the problem?

I appreciate any input and thanks in advance.
