Weird program behavior & BSoD

I did come up with something new, but not much
The BC code was again 50, but the cause was a bit different (but that is not too significant). It indicates dxgmms1.sys as the offending driver.
dxgmms1.sys crash – Blue Screen Of Death

You may want to update, your nvidia drivers

In addition, I have found that you have SPTD as a driver. That is a known cause of BSOD; uninstall using the uninstall tool.
Please remove any CD virtualization programs such as Daemon Tools and Alcohol 120%. They use a driver, found in your dmp, sptd.sys, that is notorious for causing BSODs. Use this SPTD uninstaller when you're done:

This dump indicates eamon.sys, which is your antivirus. Unisntall with the uninstall tool and download Microsoft Security Essentials, which has never been known to cause a problem with Windows.

The other dump show, the Video card, again. Update your video drivers.
Nvida or otherwise.

Dont be discouraged, this is the way the minidumps work. Either they give a clear answer, which is not often or they give clues, the more the better.

It may not be Nvdiia, but it is your graphics driver that was mentioned. Go to device manager and check you drivers, especailly the graphics. Look for outdated drivers or yellow warning markers.

It says probably memory corruption
Take this test run for at least 6-8 scans, overnight is good
Then if you pass take a good stick and test each slot
