I have been getting BSOD for a couple of days

[Sourabhkj]

So I have been getting this BSOD for the past couple of days while starting my laptop (not every time). Though it automatically resolves itself and then I normally use my laptop. But every time there is different issue which gets shown on BSOD. The issues I have come across till now are-  

Stop Code- SYSTEM THREAD EXCEPTION NOT HANDLED

- KERNAL SECURITY CHECK FAILURE

- MEMORY MANAGEMENT

- PAGE FAULT IN NONPAGED AREA

 I did every memory test either it be windows own or via MemTest86, but both these results showed pass. This issue, as far as I have noticed, happens when I start my laptop many hours after turning it off. 

  Also attached is the dump file.

I see that you ran memory tests but have you run the hard drive diagnostics from F2?

I suggest that you do that as a failing hard drive might cause those problems.

To run the Diagnostics routine, Start tapping the Esc key BEFORE starting the PC and then press the start button.
Keep tapping the Esc key until a popup menu shows. Then pick Diagnostics from that popup menu, F2.
Report back with the results.

Thanks for the help. Today I ran the Hard drive test as well and that passed.  What should I do now?

Those errors listed in the first post are from Windows.  Since the memory and hard drive have been shown good, then you can start looking for each error cause.  For the System Thread Exception Not Handled, look at this article

https://www.techolac.com/system-thread-exception-not-handled/

Start going thru the steps outlined there.  If that error occurred with a file named with that error, that would make finding the culprit easier but maybe as the errors still persist, some extra information will show up.

BTW: as it is obvious there are problems, it is good practice to start making backups of the PC to a removable media , such as an external hard drive.  Use software that will/can make a complete restore of the system, should an unexplained and sudden failure happen and the whole thing is lost.  Macrium Refelct is free and can do that and will make rescue media for you, which can be used for complete restore after a failure.
