Dear cianfitzsimons,in this case I recommend that you try the following;
Go to Task Manager and click on Processes;
Locate the Windows Explorer process and right-click on it;
Select end task;
If the screen is completely black, press together the keys: Ctrl + Shift + Esc to open the Task Manager;
Click File > Run New Task;
Type: explorer.exe check the option "Create this task with administrative privileges" and click OK;
Run the system file checker;
Press the Windows + X keys, select Command Prompt (Admin), copy and paste the commands below and press enter after each command.
Sfc /ScanNow
Dism /Online /Cleanup-image /RestoreHealth
Wait for the process to finish and restart the pc;
Check if the behavior persists;
I hope I helped, even more!
