You might want to check if there is an updated driver for this?
Code:
* MMCSS => \SystemRoot\system32\drivers\mmcss.sys [Incorrect ImagePath]
* SystemEventsBroker => %SystemRoot%\system32\svchost.exe -k DcomLaunch [Incorrect ImagePath]
* WSService => %SystemRoot%\System32\svchost.exe -k wsappx [Incorrect ImagePath]
* CompositeBus => \SystemRoot\System32\DriverStore\FileRepository\compositebus.inf_amd64_912dfdedc3d2f520\CompositeBus.sys [Incorrect ImagePath]
These can probably be fixed using DISM tool, would you agree @essenbe? [Although the SFC (below) doesn't mention these.]
The "missing services" tends to be a bug that shows up in RKILL every once and a while.
Repair install. I have far too many programs and settings to consider a clean install. That would have to be an absolutely last resort - and I probably would leave this Earth before I was done - seriously! Being a caregiver takes up almost all of my time. Now I'm going to see what else you folks requested and try to upload that. Probably the sfc details.
Understood about the caregiver stuff. 
Can you please provide the list of installed programs, using Ccleaner?

ANOTHER CLUE: I've noticed that my CPU usage approaches 100% momentarily just before the blinking cycle starts.
Open Task Manager and go to the Details tab. Click at the top of the column CPU to sort by descending usage. Watch it and see if you can identify the process which peaks at that moment - it may give us a clue.

AdwCleaner only found a lot of PUPs. I deleted them all.
Please upload the log. I can be found at C:\AdwCleaner\

Sorry - I didn't expect to post what you wanted piecemeal - but that's the way it's working out.
Not a problem at all.

The opencl.dll is a Windows bug - nothing is wrong with your SFC scan. What version Windows do you have on this thing? I thought this bug was fixed by MS.
