Guys, Claymore miner has nothing to do with this issue, it was a win10 update that did this... just look into the Device Manager and see if the cards are ok, not with the yellow triangle (code 43).
https://bitcointalk.org/index.php?topic=1921225 It must be because after updating all my machines with the windows patch, I came home last night to 8 of my miners down and the video drivers uninstalled. Today I came home to 8 more with the same problem and I was beginning to wonder if I have a virus. This windows update is a trainwreck if it is the culprit.
I agree. 5 of my rigs went down, had to DDU and reinstall drivers, and 2 went back down today, same issue. Really annoying to have to try to fix remotely while at work.
I am doing the same, make sure you go into your update and security folder and uninstall the update, it seems to keep interfering with the drivers
