I'm struggling to find anything in these dump files apart from a few windows functions that involve BLOBS.

Memtest86 will test your RAM

information   Information

Run Memtest86 for at least 8 passes so we get enough information to confirm that your RAM isn't failing

If memtest86 comes back clean then try Driver Verifier.

Enable driver verifier but only enable the options: Standard settings and IRP logging step 3.
Don't enable Force Pending I/O Requests

Enable Driver Verifier to monitor the drivers.
Driver Verifier -Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

information   Information

We use Driver Verifier as it puts a stress on the drivers, and so it makes the unstable drivers crash. This should flag the driver responsible in the dump file.

Driver Verifier will make the system laggy, this is normal so don't worry.

Before enabling DV, make sure that you have earlier System restore points made in your computer.

If there are no points, make a System Restore Point Manually

Post back the results.

The latest versions of display drivers at the moment seem to be causing quite a lot of issues.
Roll back using the device manager and see if the issue persists.

Your AMD driver is in fact causing issues.

BugCheck D5, {fffff9802552c2a8, 0, fffff880130e47de, 0}

Unable to load image atikmdag.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for atikmdag.sys
*** ERROR: Module load completed but symbols could not be loaded for atikmdag.sys

Could not read faulting driver name
Probably caused by : atikmdag.sys ( atikmdag+bf7de )
This bugcheck indicates that a pool header in memory was referenced after is was freed, in other words after a pool is wiped clean or "freed" it removes all information regarding the previous driver, if the driver still uses the same pointer to the old address it can cause issues which is why the system bugchecks.
