windows 10 Blurred and stuck on the login screen (fuzzy blurry)

Hey friends,

First this is the hardware I have on the computer :

Motherboard Name: Intel Pearl Creek DG31PR

CPU Type: DualCore Intel Core 2 Duo E7200, 2533 MHz (9.5 x 267)

Memory : 4GB DDR2

System operation is windows 10 on ssd drive.

I have a strange computer problem that started yesterday

The computer just goes up and gets stuck on this screen fuzzy \ blurry

The keyboard is unresponsive and nothing can be done

I don’t remember that I download or install any update or new software

That made it happen , But it may be an automatic installation of Microsoft updates.

I backed up most of the important files to another drive - with live usb boot

Safe mode not working also

And reset pc not work

I want to fix the operating system Because it has a legitimate and valid WIN 10 and OFFICE license

Does anyone have an idea how to solve the problem? And why is this happening?

Thanks in advance everyone
