Sudden Black Screen, Loud Fan Noise, No reaction until Force Turn Off - Issue of Windows Drivers or PC?

Hello. From time to time I get weird issues with Windows 10 or the PC itself (Notebook I mean).

( Intel i5 11 generation, Iris Xe, 8 Gb RAM, All drivers and updates installed. )

From time to time my PC is suddenly happening to get black screen, loud fan noise and no reaction at all. It's not regular thing, rather once a month or so, but still it's annoying when I write something and suddenly PC stops responding.

Additionally, I realised myself that after clean install system, doing the /sfc scannow makes this laptop show "there are corrupted files".

That happened since the beginning of having this PC (the first time i reinstalled system was 1 month since it was new).

I must admit that the same source of clean install system didn't show "there are corrupted files" after installing system on other pc (Here i mean Media Creation Tool, Official from Microsoft Site).

Back to the topic -- the issue last night happened (suddenly while writing - black screen, loud fan noise (in battery like SHHHH ----- SHHHHHH ------ SHHHHH ....; on the cable power cord SHHHHHHHHHHHH without pause), keyboard backlit, no response even on clicking shortly on 'turn off button', need to hold this key for longer time to make it turn off. I must add that all the lights from "PC turned on" is working when it hanged. It's like the screen got black and no responding while the pc is still turned on.

What i saw in the Windows 10 after turn on:

• Your C partition is broken, fix your hard drive notification.
• Lot of registered notes "C Partition corrupted" over 20 i guess within 5 mins or so.

List of registered notes in Windows:

(My own translation of these notes, as I don't use English version of Windows)

• Driver \ WudfRd \ Detection Verification failed to load
• Volume C detected fatal errors C \ Device \ Harddisk needs fixing
• Broken Structure in C \ Windows Folders
• Table MFT has broken file record C \ Windows Folders issues there
• Table MFT no name found in some folders
• WiFi Driver Not working properly

This time mainly the issue with C Parition appeared; previously (as this issue happens like once a month, out of sudden while writing or using pc); I noticed that lately Windows forced some "Optional Updates of Drivers" to install, maybe that is why? Before I was able to "not install optional updates of drivers where were Intel Media System drivers" and then the pc worked fine for few months without issue, and then someday I noticed they are gone from Optional Updates (Drivers) in Windows Update and since then the issue appeared twice.

Anyone can answer me on these issues?

1. Is there any chance that Windows 11 would fix these issues? I mean, this issue does not appear like everyday or every week, it just happens completely randomly, so for me expecting it to happen again, might take even a month, or next day.
2. Why my PC very often works so loudly (fan noise) and overheating up to even 80*C (once happened even that 90*C during 1 hour of talking on call) on simple things like browsing or making a call on PC.
3. Is there any way to prevent such overheating and sudden situation as mentioned above? Why in battery settings there's no advanced option for "Processor Maximum and Minimum Percentage of Usage" or something like that? Why PC is regularly turning off the screen (sleep mode) even if the PC has turned off Sleep Mode?
4. Any idea what is causing this issue? What is causing this issue? Someone else having same problem? It's really awful when you write on the PC and suddenly black screen and you lose everything you did at that time (e.g. written documents, etc). I waited 10 minutes and no response.

Did anyone have same issue? Is it that it must be an issue with the PC itself, or maybe Windows and Drivers?
