Hi and welcome to SevenForums.
ntoskrnl.exe is not the true cause of a crash.
Please upload your msinfo32.nfo file. To get this: Start Menu -> Type msinfo32 into the Search programs and files box -> When it opens, go to File, Save -> Save as msinfo32.nfo and save in a place you will remember -> Let it finish the process of gathering and saving the system info -> Right click the .nfo file, click send to compressed (zipped) folder -> Upload the .zip file here.
Taking a quick look at your .dmps I found some interesting stuff:
ERROR_CODE: (NTSTATUS) 0xc000000e - A device which does not exist was specified.
DISK_HARDWARE_ERROR: There was error with disk hardware
You're having loads of 7A and F4 bugchecks, these usually point toward hard driver/storage issues.
In case you have a SSD, you should get the latest firmware for it.
Upload a screenshot of your hard disk using crystal disk info:
Run Disk Check on your hard disk for file system errors and bad sectors on it:
Test your hard drive: Hard Drive Diagnostic Procedure
Test with the DOS version of Seatools as well:
Suggest you testing each stick of ram in different slots with memtest86+
Hope that helps.
