Just to check, did you completely uninstall MSE and the MSI software or just disable?
The Avira link was also for a free version but Avast is just as good.
This last dump is back to graphics again. and video memory
We saw a big improvement when the RAM voltage was increased, go back and check it has not reset back to the wrong voltage. Make sure before you leave the Bios you select Save before you exit. If the setting is still ok then increase the voltage but do not go more than 1.85V.
If you still get more BSOD's I think I will have to conclude that it is due to the RAM not being 100% compatible with your motherboard. The graphics card is most likely using part of the RAM which is giving misleading errors in the crash dumps.
The only other thing you could try is to borrow a good working graphics card from another PC, if that still causes errors then again I would have to suspect the RAM.
It would also be useful to borrow another make of RAM to test your system, preferably something that is in the motherboard compatibility list.
Another option you could try is putting the sticks in slot 2 & 4.
I would not like to advise you to buy new RAM sticks without proving that it is them first. It is up to you if you take that gamble but I would not like to be held responsible if new sticks make no difference. This is one of those occasions when I wish I had the PC infront of me.
See if you get any crashes when not running America's Army.
