Why did the programs start shutting down by themselves?

Question

Windows

Hello. It all started yesterday afternoon. When working with a computer, I began to hear the sound of the old HDD, which is used as storage. This was strange to me, since no programs or files from that disk were running. I went into performance and saw that this disk in the virtual memory section is selected "Size at the choice of the system." All other drives are "None". And disabled virtual memory on this disk. The sound disappeared, I worked for several hours, there were no problems.

In the evening, when I tried to turn on the game, it started turning off by itself. Departure was in the main menu, or departure immediately. Then Steam shut down by itself. After 3 restarts of the computer, the game still turned on, but after 40 minutes the game turned off completely and refused to turn on. I gave up on the game, opened the browser, but problems started here too: it started to freeze very badly, the tabs stopped responding to commands. Then a white screen lit up, a little later the inscription: "Hardware acceleration is disabled", "AddBlock Plus has completed its work." After the reboot, the picture was repeated.

I assumed that the computer was tired and turned it off, but today the problem is the same. I’ll say more, now when you start 3 browsers (Chrome, Yandex and Opera), one of them will definitely turn off, and some will say "Hardware acceleration is disabled." Plus, the WerFault 0xC000012D error will appear to the heap and everything will close. Previously, I could work in 3 browsers without problems, and Sublime text and Photoshop were open in the background, which I switched to from time to time. And I had enough memory for everything.

Also today, when trying to connect to another computer via AnyDesk (analogous to teamviewer), he told me that I needed more than 2GB of RAM. I closed the browser and only then did it allow the connection.

It was recommended to do /scannow on the network. He found some errors and said he left the logs in CBS.log. Here is the content of that file: https://telegra.ph/CBSLOG-08-10
To reduce the size of the log (I just don't know where I can put it so that I can watch it right away and not download it), I removed the date at the beginning of the lines ( did not touch the time) and deleted duplicate entries:
[SR] Verify complete
[SR] Verifying 100 components
[SR] Beginning Verify and Repair transaction

And another funny moment:
In the task manager for some reason it says that the memory is loaded by 57-60%. Only if you add up all the megabytes, it will come out in the region of 2.5 GB out of 8 GB. I'm sorry, but it's not 60%. I don't know if everyone is like this?

Memtest found no errors. DRweb Cureit did not find viruses either.

The temperature of all computer components is in the range from 27 to 37 degrees.

PC specifications

NVIDIA Asus 1060
SSD sata Samsung Evo and HDD Hitachi

To the question of turning on the swap file: if over the past year I have not heard the hard disk work during operation (and you can’t help but hear it, it is very loud), then the system probably did not use it for swapping and I had enough power, but only since yesterday problems started. Plus, I want to note that when I heard the HDD work, then all programs began to freeze. That is, conditionally, I click on closing the browser > I start to hear the HDD buzzing > the computer freezes for 7 seconds > the buzzing stops > the browser closes. I mean, it's not so much annoying as it is waiting for the HDD to finish recording.

Answer 1

1. check for HDD failure = the sound is alarming
2. return the paging file
