I'm getting a blue screen every time after about 10 minutes of gameplay.

2 clients on 1 box with autohotkey. Both clients running on one widescreen monitor, windowed side to side.

Anyone else encounter this problem?

I'm hoping that someone found a simple solution because I'm out of ideas on what could be causing this problem. My system is fully updated and WoW has never blue screened for me before.
