High CPU usage and corrupt files from sfc /scannow

Windows 8


Newbie here. I've been having trouble running a program called Plex (becomes unresponsive after some time but does not crash) and after a week of troubleshooting, I was able to verify that it was Windows causing the issue. I noticed that when I opened task manager, "Host Process for Windows Tasks" would be pushing the CPU to over 50%. A user on another forum told me to check the event log. There were errors with "svchost" and an item that had "tasks" at the beginning. I also ran sfc /scannow - "Windows Resource Protection found corrupt files but was unable to fix some of them". I've uploaded the CBS.log because I'm not familiar with the terminology. Could somebody please help me?

Bump?

I've already ran sfc /scannow. I attached the results to the first post as CBS.log. That's what I'm having trouble with is figuring out what's causing the corrupt files.

@Yard Dog: I don't have the installation DVD anymore

@Layback Bear: I ran the SFC /SCANNOW 3 times and restart after each time and I also ran it when Plex was not installed.
