Intermittent Game Freezing

[Pyronost]

Alrighty, lookin for a wee bit of help here.

I seem to be freezing at a semi-regular interval every two minutes or so. Now while I'm grouping, it's not really a big deal since I'm just twisting songs and slapping on things. However, when I go to AE kite, this shit is deadly, and makes one of the best sources of bard exp completely invalid.

This isnt a slowdown/speed up issue as most quad/dual core problems I see on here, but a complete 2 second freeze. Ideas?
