Other bugchecks point to different problems, and one of them even the NT module for ntkrnlmp.exe, which is simply very unlikely. This bugcheck refers to excessive paged pool usage, and likely caused by a graphics driver crossing over and passing bad data to the kernel. Hence why ntkrnlmp.exe shows up as a cause in one of them. The other BSOD shows "explorer.exe" I believe as the cause? That's also unimportant anyway.
To verify, here's what I would suggest. Firstly, we'll do a memory test...
1) Download and run
Memtest86 on boot:
http://www.memtest86.com
Make sure to let it run and do it's thing for about the first 6 tests. If it passes those, then everything should be good, otherwise any failure to pass those tests indicates a corruption in your memory.
If you get an error on one of the tests, then you should try by booting up your computer with each RAM inserted separately one at a time. When you find one that doesn't return any errors then test it in every single RAM slot to test for a bad socket.
You're last minidump would seem the most accurate to me; atikmdag.sys, being the graphics driver on your machine.
1) Download
DriverSweeper and Uninstall your AMD Graphics Driver
2) Make
sure to reboot after the uninstall!
3) Reinstall, and reboot once more
Let your machine run for around 48 hours of operation (whether you use it or not in this timeframe from time to time) and see if it BSOD's again.
