Hi
I have the same issue where in "LOWER HALF the SCREEN" is garbled and UPPER half of the screen is intact.
The following are the sequence of events:
1. I was running an old Intel CPU HW.
2. The OS upgrade was done to 1803 (There was one reboot that was done after the upgrade). 32-bit OS for x64 based processor.
3. Post this I upgraded the HW to Inteli7-7700CPU with GA-H270M-D3H Motherboard(has Intel H270 Express Chipset). I have NO other specific add-in card or graphics cards and is running with default configuration.
When I booted in "Clean boot mode" (as per your initial suggestion) the screen comes in full display without any issue. I uninstalled few old SW. I re-booted again, but screen was again in same old garbled state(LOWER
Half garbled, UPPER HALF is intact).
I found Mcfaee anti-virus as the only running services in this boot. I uninstalled them and rebooted and found the display in the same mode.
I rebooted again in "Clean boot mode" and ran
"DISM.exe /Online /Cleanup-image /Restorehealth"
and later
"sfc /scannow". The following is the output
~~~~~~~~~~~~~~~~~~~~~~~~~
