Hello. Receantly i needed to reinstall the system from windows 10 to windows 7. Everything went ok but then i started mining eth.
Before update it looked liek this: https://imgur.com/a/YJ0CF
But after the reinstall it looked like this: https://imgur.com/a/uGh4N
Only thing i changed was adding 1 more hard drive and of course the system. I dont really know why the shares went so low
