Computer stuck at moving cursor

With limited information, what we can do to help is limited. What you can do to quickly check if it’s an SSD failure, check if the hard drive shows up in the BIOS — oftentimes, failed drives do not show properly in the BIOS under the boot options, or instead of showing as something like “Samsung PM951 256GB”, it shows as if a cat was on the keyboard.

If the drive shows up correctly, check the SMART status to make sure it’s okay with something like Parted Magic (paid by author, but GNU Public license means redistribution is legal so other sites host it). The issue with free downloads is it’s “as-is”. If you see it passes, then what you can do is read the drive and make sure the structure isn’t off, which may indicate OS corruption. If you do not want to pay for it, look up “parted magic download” and make sure the site isn’t too shady. This is a little older than the current version, but it’s not from a shady site.

If the drive doesn’t look corrupted, you may be able to fix it by reloading the MBR with a Windows 10 boot drive using bootrec.exe \fixmbr. It doesn’t always work, but it’s your best realistic chance to dodge a Windows reinstall.
