After analysing your minidump, I believe the culprit is faulty ram. Reseat the memory to another memory slot and clean the dust inside the memory slot. If it still crashes, run memtest to stress test the ram.
The debug report of your minidumps indicate that the culprit is faulty ram.
Some faulty ram can pass memtest. If you have good ram at another PC, swap the ram and see what happen. You can post your problem to another forum to ask for help.
