Windows 10: PC reverts back to earlier state, doesn't let me safe boot or re install windows

Version 21H2 OS Build 19044.2364 I have 1 SSD and 1 HDD, will be needed for laterIt has been 2-3 days since my PC started acting weird. It has created a lot of problems and the more I try to fix it the more I realise it's even more broken.It all started with the PC crashing with no apparent reason and restarting, this happened a couple of times until I noticed that any change I made was reverted after each restart downloads, installing files, deleting files , logging in accounts etcDuring this time it has been going through phases of freezing and is very slow in generalAfter that I start

Window 10 reverting to earlier state after reboot:

Hi, member here

as above, a recently new installation of 10 is reverting back to an earlier state before reboot, mostly an immediate earlier state but sometimes for games a bit earlier, so eg witcher 3 save games, go back to an earlier part of a battle even if saved, docs sometimes go back to immediate earlier state, or sometimes are ok. M/Support say they are aware of the issue, but as they were helping me the PC crashed.

have reasonably decent knowledge of W10

Thanks again!!

I`m sorry I had not noticed that the text on the picture was in spanish. It says that windows has replaced some damaged clusters in "name" file and "directory". Then, at the end "an unspecified error occurred (75736e6a726e6c2e 4f6)".

I`ll do it and I`ll be updating this thread when I have the report.

I ran SeaTools. These are the results:




Does it mean my HDD is useless?
