Yep, that's exactly how Phenom freezes. Mouse can move but everything else is locked!

There was supposed to be a new version of AOD coming last week. It should be out soon and is better. AOD is what freezes my system up too and it doesn't let you do any oc properly. But then again, if HT has stopped booting at 'xMHz' then your HT ref. limit/CPU speed limit won't be far off anyway.

I can't boot mine at anything above HT ref. 222 now. Before I booted 265HT ref. max. and 270 within windows.
