Windows 10: Motherboard change on laptop, windows key doesn't work on the same laptop0x800705B4

Last month or so, my laptop had a problem with its motherboard and had it sent to shop for replacement of its motherboard, 2 months laterPandemic happenedi was able to get it back with a new motherboard and upon getting my laptop, i have an error that says"The last product key you entered can't be used on this copy of Windows and on the Troubleshoot Windows Activation, even after clicking the "I changed hardware on this device recently" and after doing so the laptop that im using isn't connected to my account even though I've connected my account to my laptop before, i even have my phone and pc linked with the Your Phone Companion app.


how do i proceed with this since troubleshooting doesn't even seem to help.

Windows doesn`t start. Authomatic repair doesn`t work.

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?

Thanks for your answer, ken!

I deleted all my data. I had have it backed up.

I did a clean installation using the windows media creation tool (usb option).

No, I didn`t. I thought a clean installation would solve the problem.

After posting my previous message, I did it.





After chkdsk, I close cmd and tried to boot and the laptop just turned it off. This morning I`ve restarted it and automatically windows did a repair. Windows has booted and it seems that the repair tool has removed chrome and acrobat pdf reader (the only two programs I had installed after reinstalling windows).

Now Windows is installing updates and restarting my lapop, I`m kind of frightened. I don`t want it to happen again. Anyhow, I want to know what has brought the issue

I`ve been looking for information about the error code at the end of the picture and I didn`t get anywhere.
