I'm getting Black Screens too (normally requiring a hard boot) on a sometimes regular and sometimes an infrequent and (apparently) random basis[1] with an ASUS Radeon R9 290 DirectCU II (R9290-DC2OC-4GD5) at standard clock/voltage and v16.9.2 AMD Radeon driver (also in earlier v16.9.1) in Windows 10 (latest updates) in Chrome, Edge, other programs and sometimes even when just showing desktop. Oddly, when in the graphics intensive simulator/game Trainz:a New Era Black Screens appear less frequent.
There is no overheating, case, GPU, CPU fans etc. all clear of dust, Corsair 760W PSU, GPU & CPU (Intel i5-2500K 3.30 GHz) pass in Furmark, RAM passes in MemTest (bootable flask drive). All pass ASUS diagnostics.
When the Black Screen happens, sometimes (but not always) GraphicDrivers\UnsupportedMonitorModesAllowed is set to 1 (as well 'Hide modes that this monitor cannot display' check box being cleared). As it should, setting the latter always clears the former, but I am not convinced that this is, on its own, the cause of the Black Screen. Notably disk access stops completely just after the Black Screen, indicating a tight loop with interrupts off. As a further indication of this, I do sometimes get a THREAD_STUCK_IN_DEVICE_DRIVER error notification.
I have tried completely removing AMD Radeon software with Guru3D's Display Driver Uninstaller DDU and reinstalling, disabling all Chrome extensions, removing many programs, doing Virus and Malware scans, getting Windows 10 to do a self-check and more.I have also tried changing the monitor (maybe without a reboot, my normal one is an AOC 2969PM 21:9 monitor).
Help!
Peter.
