Windows 7: Intermittent BSOD with World of Tanks

Hello, long time reader, first time poster here.

I have a nicely working midi tower system which handles most of my home computing: games, video, music, development, emails, etc. It performs fine with most games including Shogun Total War, Blood Bowl. It rarely crashes.

Recently I started playing World of Tanks version 0.6.7 and the system dies via BSOD. Some nights I have none. Some nights I cannot escape them.



I've attached the DMP, system info, and perfmon files. Please let me know if I can perform any other diags. I appreciate all the help and information here!

Thanks, Dan
System Info:
Win 7 Pro x64
Intel x58 mobo with i7 920
8 GB memory
EVGA GeForce GTX 570,
Realtek HD Audio

1st minidump:
TERMINAL_SERVER_DRIVER_MADE_INCORRECT_MEMORY_REFERENCE (cf)
Usually caused by driver.

The First minidump indicates csrss.exe, possible malware hiding place.

Scan using malwarebytes:
Malwarebytes Anti-Malware - Free software downloads and software reviews - CNET Download.com

Also ensure you are using Microsoft Security Essentials. If not, then uninstall other antivirus and install MSE:
Microsoft Security Essentials

Last minidump:
PAGE_FAULT_IN_NONPAGED_AREA (50)
Usual causes: Defective hardware (particularly memory - but not just RAM), Faulty system service, Antivirus, Device driver, NTFS corruption, BIOS

Your last minidump is indicating "dxgmms1.sys", which is a Direct X file. you should update your video drivers from the Nvidia site.

Also, make sure to remove old drivers using driver sweeper. Follow all instructions, then install the most recent drivers, nonbeta. I usually download(dont install) the drivers first so they are already there to just install after everything is cleaned by sweeper.

You should also enable driver verifier to get some more minidump files to analyze and run memtest86+, as bad ram causes a lot of problems.

Follow all instructions carefully, and make sure you run memtest for atleast 7 full passes.
