Hello everyone,
I have had blue screen issues for quite a long time and tried a lot of things to fix these issues but I have yet to find a soluation.
That is why I am hoping I might be helped here.

First of all, my hardware:

Mainboard: Asus M4A89GTD-PRO/USB3
Processor : AMD Phenom II X6 1090T @ 3200MHz
GPU : Zotac GeForce GTX 660 Ti
RAM : Corsair XMS3 PC-1333 8GB (2x4)
HDD: Hitachi HDT721010SLA360 ATA Device (1000GB)
Power Supply: LC-Power 6600 (600W)
DVD-Rom: Toshiba-Samsung DVD-ROM SH-D162C
OS: Windows 7 Home Premium Home Edition Media Center 6.01.7601 Service Pack 1 (64-bit)

I did not manually overclock and have the onboard GPU disabled in the BIOS.

The problem:
While playing games like Battlefield 3, Guild Wars 2 or TERA Online on high settings I get a blueescreen after a varying time - from 5 to 20 minutes of playing those games.
Programs like Photoshop, Google Chrome or VLC run for hours without causing bluescreens.

List of the bluescreens:









Attempted solutions:
What I tried so far is
  • Update GPU driver to the latest release
  • Bought the same RAM again and replaced the old ones
  • Ran Memtest - no errors after 5 hours of testing.
  • Update BIOS to the latest version
  • Update all Mainboard drivers (Chipset, USB, Audio, etc) to the latest version
  • Replaced GPU (from Zotac GeForce GTX 260 to the current one)
  • Replaced HDD
  • Unplugged both DVD drives

I hope the provided information are sufficient. If you need more information, feel free to ask and I shall provide them.
Hopefully you can help me with this.

  1. My first guess would be temperatures issues -- it seems your system is getting too hot.
  2. RAM. You are generating every single BSOD that is typical of a failed stick of RAM.

    Run memtest86, confirm the error, then figure out which stick is bad by testing them one at a time.
  3. What USB devices do you have? A few BSODs appear USB related. But also mentioned was NVIDIA video, HDD (specifically bugcheck 0x24 + ntfs.sys); + various other bugchecks.

    The corrupted PFN BSOD [0x4e (0x99,,,)] was interesting as it contained a 0xc000001d exception = illegal program instruction, e.g., division by zero.

    So many different bugchecks naming Windows drivers smacks of unknown hardware failure. RAM is definitely a suspect.

    For info, those naming ntroskrnl.exe, better known simply as NT = Windows NT Kernel & is merely listed as a default; same as others naming Microsoft drivers. These are NOT the cause.
