Hello there!

Today all my rigs with claymore dual miner crushed.
Rigs have different versions of claymore, starting from 11.5 up to 11.9.

What happend:
In a hour approx all rigs stops, but, windows still running. Just miner software crush without any errors, watch dog does not help.
Windows updates fully disabled. I don't touch most of rigs more then half of year (and few more then year).
Also rigs stored in fully different places and don't have any relation

I don't see any helpful logs. Looks like it is just stop working. Windows logs also don't have any thing.

After restarting all rigs, I have few crushed again in a 2 hours after restart.

What happend? Anybody facing something equal???
