I've had quite a hard time trying to troubleshoot error code 0xc0000021A upon boot, resulting in a blue screen.
So far I've only managed to boot up the machine by disabling driver signature enforcement using the advanced startup recovery options, any others won't work (even safe mode).
This leaves my machine vulnerable and unusable for some applications, so I'm looking to fix this issue.
The issue popped up recently, after installing several programs associated to graphics and games.
I've tried uninstalling (and re-installing afterwards) all of those components trying to fix the issue, without any luck.
I've ran Malwarebytes scans, Windows Defender scans, Kaspersky's TDSSKiller and some other ones - all of them with 0 infections found.
Other options in the advanced startup recovery menu don't seem to help either:
- System Restore isn't available as there are no restore points to before the point when the problem occurred.
- Windows Startup Repair can't manage to fix the issue.
- System Image Recovery isn't available as there are no recent images.
chkdsk finds no errors or bad sectors.
sfc failed several times after i managed to boot up the machine. Until i ran it from CMD in advanced startup recovery options as described here, then it said it ran succesfully once - however when running it again there are remaining issues with C:\WINDOWS\System32\aepic.dll in the CSB log:
Hashes for file member \??\C:\WINDOWS\System32\aepic.dll do not match actual file [l:9]'aepic.dll'
I don't want to grab any dll i could use to replace it with from the net, since I don't know any reliable sources for these kind of DLLs.
Also, Windows 10 is up to date.
Is there anyone who can help me out troubleshooting this issue?
I don't know where to look anymore and re-installing the machine completely isn't an option at the moment.
Any hint or direction to look in would be appreciated, thanks in advance!
