More annoyingly low fps

So I had an issue last week with low fps with my higher end system. I reinstalled my gfx drivers and it seemed to fix the problem. Since then I have been having periods of my fps suddenly dropping for no apparent reason. Now it is back to between 6-14fps, even on low settings.

Whats weird though is when I alt-tab out, such as now, and then back to WoW, my fps is around 109 and runs very smoothly. Then it goes back to 7fps within seconds.

Have you checked for overheating as advised in your previous thread?
