I was curious if anyone could give me a heads up on this. I have a rig that was mining on middlecoin for the past couple days and when i woke this morning the pc was frozen. 
This isn't typical so I restarted it and hooked back up to middlecoin and it happened again. The next time I restared I hooked up to a different pool and it hasn't frozen, is there possibly something going on with the pool to cause this? It freaked me out a bit.

Definitely not heat, and I don't believe it's hardware or driver. It's the pool that was causing it. As soon as I switched pool, the issue was gone.
Temps never got above 77°.
Anyways, I moved the rig back to middlecoin and it seems fine now. Glad H2o got it back up, thanks buddy!
Was the rig really frozen or just cgminer unresponsive ? I can imagine that maybe some connection issues caused cgminer to halt (which might have apperaed to you as a frozen rig)
just my 2 satoshis ...
I have exactly the same issue (posted on a previous page), cgminer freezes on middlecoin only, both on BAMT and Win7. My suspicion is that due to frequent switches/disconnects cgminer is more prone to issues and is ready to go over the edge at any time. I've installed the latest ATI drivers on my BAMT box last night and it didn't freeze when a cgminer on my Win7 box did (11:35 PM PST), but showed a huge drop of kh/s at that point in time.
Not trying to bash anyone or anything, just giving my view.
