0xc000021a Help!

[Icarax]

Okay so I figured that heading to this forum could help me out since I know there's some smart lads here. I have a bit of an issue....

- It all started when I overclocked my RAM speeds a few days ago. The system was fine for a couple of times but eventually the system got into a boot loop.
-I then went to remove the CMOS battery from my ASROCK b450 ProM4 Motherboard, then insert it in again for 15 seconds.
-The system booted normally to Windows 10, yay! I was then using the pc for a while, then a notification popped up, saying something like this: "Please restart your system to install urgent files"
- After a restart, the dreaded BSOD 0xc000021a appeared, and it won't go away, whatever I do!
      - I tried various commands in the cmd prompt via the advanced troubleshooting option, such as "cfkdsk /f /r", "sfc /scannow", "dism/online/cleanup-image/restorehealth", but none of them work.
      - I have also tried to disable Driver Signature Enforcement, and that didn't work.

      - Restoring the PC to an earlier point also did nothing.

-The PC cannot also get into Safe Mode.

 

Is there any way I can fix this without doing a fresh install of windows, wiping all of my data? Is there a way I can access the dism program from the troubleshooting option? Thank you guys in advance for your help!

Problem like this one may be very difficult to solve if you have no second computer with working system. And even then it may be very time consuming and difficult (some file compare tools must be used etc) or even impossible.

 

The best you can do is to image your system using bootable Macrium Reflect rescue USB (created on some other, but similar PC) so you can access your system and user files after you made clean install (you can also just copy files to another drive, but this way you may miss something).

 

At last chance (before fresh install) you can try to boot with only one, single ram stick without any oc (even without xmp). But I don't think it helps in your case.

 

If you want to be really safe and try to find problem in the future, but another SSD for made fresh install and keep old one for analysis. There is also a chance that you messed something by yourself by accidentally move some folder.

I tried just using one stick of ram to boot but nothing new happened. I also reinserted the CMOS battery, and nothing. My plan is this; I’m going to remove both of my drives, put everything important on my boot drive to a backup, then install a fresh version of windows on it. I hope this works. Thank you for your help!
