So many versatile bugchecks gives a prima facie notion of some hardware level issue. It would be the best that you test your RAM modules for possible errors.

How to Test and Diagnose RAM Issues with Memtest86+
​

Run memtest86+ for at least 8 consecutive passes.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

Let us know the results. If possible, take a camera snap of the memtest86+ screen before closing the program.
