Hello everyone,

For the past 3 DAYS I am dealing with a very serious problem regarding my Windows 10 OS. The problem happened while I was gaming when my PC froze and I had to force restart it.

After that I keep getting the "Your PC ran into a problem" blue SCREEN (image attached below) with an error labeling 0xc000021a.

I tried a bunch of google solutions and none of them seemed to be working and also none of the windows BUILD-in solutions doesn't work (both resets, repairing with win10 repair disc, restore, return to previous build, fixMBR). Also I would like to point out that every time I try to chkdsk my OS drive (C:), this OPERATION isn't allowed because "Chkdsk cannot run because the volume is in use by ANOTHER process".

I am one step away  from formatting my drive, so any help will be appreciated, although I would like to point out that I have check a lot of google solutions so please don't bring up the same solutions as answers.

Thank you for your time in advance.

[attachment deleted by admin to conserve space]Have you tried resetting Windows 10?  Settings->Update & security->Recovery->Reset this PC.

This will reinstall Windows and gives you the option of keeping your existing files.As I mentioned in my post none of the  troubleshooting mechanisms (resetting , repair , restore to a previous point , restore to a previous build) are working. I can't even get my system to boot in safe mode!It's Shift + spam F8 for Win 10 safemode...That doesnt work either
