After Win 10 update January 22, 2019—KB4476976 (OS Build 17763.292)
There was a problem with AMD Wattman
And I can not do what to do next
Many ppl have same issues and AMD is looking into it now but best make report from here:

You have new driver 19.1.1 installed correct? That is what is causing this issue for many people, you can try downloading and installing older driver(18.x.x)
