BSOD playing dota2

I receive randomly BSOD while dota2 is running with the following signature:

Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7601.2.1.0.256.1
Locale ID: 1044

Additional information about the problem:
BCCode: 1e
BCP1: 0000000000000000
BCP2: 0000000000000000

I just formated so that should not be the issue. I expect graphic drivers or RAM to be the problem.

Torris.

Code:

BugCheck 1E, {0, 0, 0, 0}

Probably caused by : ntkrnlmp.exe ( nt!KiKernelCalloutExceptionHandler+e )

Code:

Usual causes:  Device driver, hardware, System service, compatibility, Remote control programs, memory, BIOS

Code:

EXCEPTION_RECORD:  fffff88002f1ba58 -- (.exr 0xfffff88002f1ba58)
ExceptionAddress: 0000000000000000

   Parameter[1]: 0000000000000000
Attempt to execute non-executable address 0000000000000000

It seems that the driver has attempted to execute a page of virtual memory with a non-execute protection bit.

Code:

1: kd> lmvm atikmdag

Your AMD/ATI graphics card driver seems to be outdated and causing problems, please update to the latest WHQL version from here - AMD Graphics Drivers & Software

WHQL
Release Date: April 24th 2013
Version: 13.4
In Device Manager: 12.104

Note: Do not install the CCC (Catalyst Control Centre)

No AV protection? If so,

Install and perform full scans with:

• Malwarebytes : Free anti-malware download
• Microsoft Security Essentials | Protect against viruses, spyware, and other malware

   Information

Remember to install the free version of Malwarebytes not the free trail; untick the free trial box during installation. MSE is the most lightweight and compatible with the Windows 7 operating system

You can also view this thread for a complete free and lightweight security protection combination:

• Good and Free system security combination.

I still have problem after installing the suggested drivers. I also tried to format again just to make sure any old drivers got cleaned.

So now I basically got only; newest display drivers, steam and dota2. Still receive BSOD.

Please follow - Blue Screen of Death (BSOD) Posting Instructions

Do this each time you have a new BSOD, I can't provide much help without dump files.
