Aye, as I can’t find nothing problematic in logs. 
Either way, we shall use Zoek’s AutoClean mode when we are here. Zoek will in additionly check your system on malware, adware and it will clean up temp&junk files.
=> Re-run zoek.exe, click on Options > check box

for AutoClean options.
Now press

button and wait for zoek to finish his cleaning.
Post here fresh created Zoek log and tell me how’s your computer running now?
