Help!
One of my habbies died this morning. They were both happily hashing away for days @825 when I noticed that one of the habbies stopped hashing and went zombie. Tried resetting everything but same result. Tried turning hash clock down to 500 and same result. The board powers up fine, but when it's asked to hash it appears to go through a reset, over and over, each time cgminer detects it and tries hashing.
Anyone have any ideas for me to try?
*edit*
I'm getting this error from cgminer:

*edit 2*
Oops, never mind.

Just had a loose PCI-e connection.
These things are built like tanks, aren't they?
