I've looked at your dump files and you are getting several error codes and most of the blame is on your graphics card. However that could be from the game crashing. The graphics driver is the driver most used while gaming, so if the game crashes, so will the graphics driver. The one error you are receiving that concerns me the most is
Code:
Use !analyze -v to get detailed debugging information.
BugCheck C1, {fffff9806a1f4f10, fffff9806a1f4280, b140f0, 23}
Probably caused by : memory_corruption ( nt!MiCheckSpecialPoolSlop+9a )

This is the one you mentioned. The reason it concerns me most is because if you have ram errors, nothing in the dump files is reliable. So, with those errors, I have to be certain if the ram is causing the problems we are seeing. So, Please do it exactly as the instructions are given. If you have any problems or questions, feel free to ask. Please run it for a minimum of 8 complete passes all at the same time, which will take severalhours.
Please Run Memtest86+
Information
Please download from this site only
http://www.memtest.org/ in the middle of the page are the Download links, you can download the ISO.zip or the Auto USB Flash Drive installer.zip
Extract the Zip file. If you chose the ISO image, burn it to a CD using Windows Disk Image Burner or any Image burner you may have. If you downloaded the Auto USB installer, extract it, insert your USB 2.0 Flash Drive and take note of the drive letter. Run the installer, select the Flash Drive Letter, check the format box and press next. It will install memtest86+ to a flash drive. You can use either V4.20 or V5.01. Boot from your selected media. If you use V5.01 it will tell you to press certain buttons at the start, please press no buttons. The test will begin on it's own and continue to run until you stop it. It needs to run for 8 complete passes or until you receive an error. If you receive an error, stop the test. Even 1 error is a fail. Each pass tests a different part of the ram and each of the 10 tests in each pass tests something different. It takes a minimum of 8 passes to completely test the ram, more passes are better. It is quite a long test and will take several hours depending on how much ram you have. Due to the time length it is best to run overnight. If you have any questions, please do not hesitate to ask
