I've got an AntMiner S1 from one of the early auctions that just stopped mining about an hour ago. I've made no configuration changes and I've never tried to overclock it. Its on a 750W power supply all by itself and has been since the beginning.
Any ideas? If this is a warranty situation I'd like to get the process started sooner rather than later.
from dmesg:

cgminer does not show as running. Restarting it from the GUI makes it show up for a little while, then it disappears.

I'm not sure what killed cgminer but it was killed off automatically.
