I had the same problem. Updated to the new ReLive driver, and after the reboot I had like 10 seconds of time before everything went black. My only option was to reboot again, and reset my system to a 3 day old state. Try this until they release a fix for this...
Edit: I have an R9 390 Nitro
Asus Z170-A mobo
16GB Corsair vengance RAM
I Uninstalled afterburner, asus gpu tweak and put avast into passive mode rebooted installed the driver and rebooted again. It worked
