error Oxc000021a !!!!!

hi,

would like solution for this

a week ago when i opened my laptop, i got this error message.

• :(
• Your PC ran into Problem and it needs to restart. We're just collecting some error info, and then we'll restart for you.
• error. 0xc000021a

After it automatically restart it says

• After multiple tries, the operating system on your pc failed to start, so it needs to be repaired
• Diagnosing your pc
• Automatic repair couldn't repair your pc
• press Advanced Options to try other options to repair your pc or shut down to turn off your pc.
•  Log file: C:\Windows\System32\Logfiles\Srt\SrtTrail.txt .

after this i ran the diagnostics ,  i did a quick scan and then through testing, everything is fine, all test were passed but in the result section it showed error - 2000-0333 video-user provided no input for graphic test.
