Fried GPU
Does that come with ranch?
 sorry >.< 
For .25 BTC shipped it does!  

In years of troubleshooting I've lost video cards, but the behavior on this one that had been mining was  not the typical no post, blue screen, lock up or stability issue  it just works solid until it bombs out and doesn't, can stop the miner at which time it cools off very fast and restart it and it goes again for a few minutes wash rinse repeat.  I suppose I could setup safe temp limits and gpu restarts until it goes completely, but just getting some verification....
