So I have a odd one.
Essentially when ever I wake my pc, explorer has crashed. No background. Taskbar is white, desktop icons are glitched and showing over two screens (second screen is normally empty)

have performed a chkdsk /r
a sfc scan

No help so ended up using the inbuilt reset computer.
Was fine for a day then the same reoccurred.

Only other thing I have changed was to upgrade the monitors from twin 24in 1080p Phillips to twin 27in 4k Dells.

Has anyone come across something similar, I'm thinking possibly hardware related from the new monitors, either the monitors or the on-board gpu not liking the 4k (no help changing resolution to 1080).
But if hardware then I don't understand why this would cause explorer to hang.
