The crash dumps are not pointing to anything precisely. But it is memory related. Not necessarily the physical RAM, it may be any driver too, passing bad info to the memory. Let us explore both the possibilities.
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.
Information
Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.
How Can we know that DV is enabled:
It will make the system bit of slow, laggy.
Warning
Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.
If you fail to get on the Desktop because of DV, Boot into Advanced Boot Options > Safe mode. Disable DV there. Now boot normally again, and try following the instruction of enabling DV again.
