I have a problem with latest drivers 17.2. After driver installation error pops up that you can not verify the digital signature and the driver does not work properly. I would add that when you install version 17.1.2 everything is working properly. Computer recently after format even did it twice to be sure, and something is wrong with this driver.
System:Windows 10 x64
Graphics Card: R9 290 X
Yes it is known issue. Just use previous working driver for now. 17.1.2 for example.
