BSOD at random moments, ntoskrnl is the reason, don't know how to fix

So I have problem with my computer again, but this time it creates .dmp file.

So, what I've already done to prevent BSOD from happening:
1. Reinstalled Windows 2 times. First time on SSD, second time on HDD and BSOD is still hapenning.
2. Checked HDD and SSD connection to power supply.
3. I checked every RAM memory stick, I mean I plugged one at time, and BSOD happened with all of them, so it may be that all my RAM is broken, or it's not RAM.

Can you help me with that crap?

EDIT:
Mostly it happens after like 20 or 30 minutes of working on computer.

Please visit Windows Update and install all available updates (exception for Windows 10 update)
Updating helps improving system stability, performance and fixes several problems including BSOD's.

It appears that the dump present is corrupted (the size is 0KB) so it is useless, the event logs however show a few 0xF4 which in my experience is caused by hard drive failure.
Please make sure your installation is up to date and test your system, after you have tested your system and it appears to still crash then follow below instructions.

Diagnostics Test

 HDD TEST

Run SeaTools to check the integrity of your HDD. SeaTools for DOS and Windows - How to Use - Windows 7 Help Forums
Run following tests

If the short generic fails, no need for the long generic.

   Note

Do not run SeaTools on an SSD as the results will be invalid.

Diagnostics Test

 System File Check

Please try following:

• Open an admin command prompt
• Copy/paste "sfc/scannow" (without quotes) and press enter
• When it finished reboot your system
• Open again an admin command prompt
• Enter sfc/scannow again

If sfc/scannow says "Windows Resource Protection found corrupt files but was unable to fix some of them" after the second SFC, please upload the cbs.log file located at {windows partition}\Windows\Logs\CBS\, if the file is too large try a 3rd party uploader like dropbox, onedrive, google drive, mediafire etc.
System File Check(SFC a.k.a. Windows Resource Protection) needs to have your system rebooted in order for sfc to try to fix the problems that it finds.

Search for updates a few times, it sometimes takes a few attempts to find updates.

Is the firmware of your SSD updated?
