Windows 10: Check disk not running / stuck / failed

Hello,

I am having a problem with my uncles computer, so I will describe the problem my best.

Basically, the cause of this is unknown. When PC is booted, the Check Disk automatically starts. When I cancel Check Disc before it starts, I can access WIN10, but it is SLOW and basically no programs work (not even cmd). I can not even run programs to check what is the problem. Also, some files are missing, so maybe PC starts in safe mode.

When I let Check Disk to run, it starts and at first stage, it gets stuck on 1%. I have let it stay for +18 hours - still stuck at 1%.

In conclusion, when I boot WIN 10 it is slow and gets stuck. When I let PC boot Check Disk it also does not work. I am thinking, that the disk drive may got damaged, but it is a desktop and "shutting down" has been done like it should be.

Does anyone have an idea, what can cause this problem? Because I am out of ideas.

I am going to prepare WIN 10 repair on USB drive, hoping that maybe the update is the reason. Before that I try to let the Check Disk run for 2-3 days.

TLR - WIN 10 and CHECK DISK do not work.

Checking Disk Consistency

Ok i did as viper suggested, but it stops checking at stage 3. It is still saying the drive is dirty, and still needs to be checked. I did a defrag and a disk cleanup, and suggestions?

 

Disk Check Issue?

I'm having the Disk Check issue again. However, this time, I can't use Startup Repair to fix it. Can you address this?

 

Stuck in Windows 10 Upgrade

My computer seems to be stuck in a Windows 10 failed upgrade loop. I was running fine on a beta version of Windows 10, and then I came downstairs one morning to see it repeatedly booting, attempting to repair, then rebooting. The steps I've taken to diagnose are:

• Attempting to boot off a USB drive (with all drives disabled in BIOS) - this fails at the point of the blue windows screen
  
• Attempting to boot the machine itself and getting into "repair/safe mode" using F7
  
• Looking at the BIOS for obvious failures (e.g. RAM that should be there is missing) - nothing obvious is wrong.
  

I am fairly certain the build version was 9926. For many months, the system would attempt to upgrade, and then say "it failed" for some reason and roll back.

Suggestions for next steps?
