There was a windows update that stops the miner from running. Back to EWBF until this is resolved.
. I also experienced a lot of issues after recent windows update. Using zm 0.5.4 , few miners ran into some loop at random times , also had to lower memory clocks on cards although they ran for month straight without any issues . Also performance is lower I was getting around 10170 sole now 10000 and lower

anyone had this loop with version 0.5.4 ?
