Task Manager Shows Extremely High Resource Usage: Memory (RAM) & CPU :: SFC & DISM Fix Not Working - Windows 8.1

Device: ASUS T100A v1 Notebook
RAM: 2GB
OS: Windows 8.1

BACKGROUND
My Google "Chrome" browser was loading pages slowly so I looked at the Task Manager. I turned off services and processes that seemed not needed, such as Acrobat update. But Memory still shows 65% and CPU 45-70%. After reading some forum posts, I attempted SFC /scannow, which led to DSIM in a "Command" shell window (launched as administrator).

QUESTION
How can I recover to a stable system with all system files functioning properly and not corrupted?

FILES
I am attaching a file that contains the Command shell commands and output as displayed on the screen.

SFC---DISM-Errors-20190813.txt

If you need the windir\Logs\CBS\CBS.log or DISM.log files, let me know.

Download windows 8.1 setup and start it within your running windows session.
It will offer to "upgrade" your OS, which is nothing but a repair installation, keeping programs and settings and files. Afterwards, see that you reinstall all updates.

In addition to McKnife's suggestion:

1. Run Admin Tools, Resource Monitor for 15 to 20 minutes and then look in the Memory and CPU sections to see what processes are using Memory and CPU.   Using memory may be a function of the number of Chrome tabs and other applications and not be an issue. High CPU is an issue to resolve.

2. Consider upgrading to Windows 10. From Windows 8.1, upgrading to Windows 10 should work.

You both missed one critical question here, how many chrome tabs did you have open at the time?

Chrome is absolutely shocking for memory, it's coding is utter crap. Give firefox a try instead as it uses significantly less memory and works pretty well on the 4GB laptops we have in the office.

To put this in perspective, chrome on my home machine with 16GB of memory uses 6GB of memory when I open up 5 - 10 tabs.

you also have a really old system with little memory so not surprised at what you are seeing
you can try your repair options as mentioned, though even fixing that i don't expect to see much of any difference considering the hardware
with the little memory, the system could also be doing a lot of page swapping which will impact performance

So far there is nothing to conclusively say there is anything abnormal with the system. With the loads if JavaScript constantly running in web pages these days, its not uncommon at all for just a few web pages to take CPU from between 50 to 75%. My personal laptop seems to idle at about 25% CPU with no active user programs.

A device with only 2 GB RAM is barely useful these days. 4 GB is generally absolute minimum, with 6-8 GB often the standard for a machine to be useful.

What you really need is new hardware or at least a RAM upgrade if that is available.

@Alex
"Chrome is absolutely shocking for memory, it's coding is utter crap" - I don't agree. Although this is a little off-topic, you may want to share the websites that your chrome has open that use 6 GB of RAM.

FYI, I have a RD server 2019 here ,that is used for browsing. At the moment, 294 chrome.exe processes are open (please note, that that could equal 294 tabs, but it could be less tabs than that), that use 16.9 GB of RAM. That equals about 57 MB per process, where your situation would reflect between 600-1200MB per tab. Sorry, but that does not add up and is all but normal. (latest chrome here)

Try opening the browser with 10 different sites in 10 tabs. You will probably notice that Google Chrome uses significantly more memory than single-process browsers do for this case.

And that's off of the chromium website.

Google for the win, chrome is renowned for being a memory hog.

Those are several good ideas.

Regarding the machine having only 2G memory, it has been adequate. The slowing down is a one-time thing. My real concern is that I cannot recover system files using SFC.

First thing I'll do is make a backup image using Macrium to a 64gb USB Flash drive.
Then I want to attempt to get SFC to recover the system files properly according to McKnife's suggestion.

One thing I notice now, however, the browser is not as slow as it had been before I ran SFC and DISM, even with the errors. Hmmm.

SFC fixes errors and that could be why

Alex, you quote the chromium site. However, it's from 2008.

My point is, you cannot just name chrome a bad browser and memory hog and try to make it responsible for high resource usage in general. Browsers may leak memory, yes, and I have seen single chrome tabs that users kept open for days use up to 1600 MB of RAM. But be sure, that is far from normal - I administer chrome for 50 users on a single machine, I know a lot about how it behaves.

It may be from 2008, however chrome still uses the multiple processes configuration, as such still uses more memory.

And I also administered it at John Lewis for 40k people, I know how crap it is.

Good, so you know how crap it is. Then tell me, what 10 sites do I need to open to see 6 GB of RAM usage?
Then we can compare this to firefox.
