BSOD after multiple events

Hi there,

I'm getting BSOD at multiple events such as return to Windos while playing Battlefield 4, in general switching between several windows. It's there for several months and occiurs from time to time. Reseting works after BSOD and windows starts normally.

System and bluescreenview stats are in the pictures below

Please help me with this problem!

Use !analyze -v to get detailed debugging information.

Could not read faulting driver name
Probably caused by : win32k.sys ( win32k!SFMLOGICALSURFACE::OwnsSurfaceCleanup+2d )

most of your dump files are similar to the above and can mean that something was installed that is faulty or you have NTFS (HDD) issues. Anti-Virus apps can cause it as well as defective RAM. Your system does need quite a few updates however:
Your missing a service pack which is critical for stability and security. Please download and install SP1 here:
If you encounter issues installing the service pack then you may need the update readiness tool:

Please run a chkdsk:

avgntflt.sys Wed Apr 30 17:34:29 2014: Avira AV please remove for the duration of this debug and install MSE which is very stable:

atikmdag.sys Fri Dec 06 21:19:43 2013: AMD GPU driver please update:

nusb3hub.sys Fri Nov 19 01:34:24 2010: NEC Electronics USB 3.0 Host Controller Driver (previous BSOD issues with 2010 and earlier versions). Your actual USB3 contoller is a NEC uPD720200 and the latest drivers can be found at the bottom of this page here:

Rt64win7.sys Thu Jan 13 11:57:19 2011: Realtek RTL8168D/8111D Family PCI-E Gigabit Ethernet please update:

RTKVHD64.sys Tue May 10 11:22:00 2011: Realtek High Definition Audio Function Driver please update:

RtNdPt60.sys Mon Jul 20 03:27:32 2009: Realtek Ethernet Diagnostic driver please update:
(5th download down)

If after making the above changes you still get the bsod then you need to test your RAM.
Windows does have it's own memory testing app but it can often miss errors and the best app for the job is Memtest86. The latest version of which can be found here:

To run Memtest86 you need to either burn a copy of it to disk or use a USB stick. If you look down the page you'll eventually find the latest version and it's associated downloads. If your burning to disk choose the pre-compiled iso zip. If your using a USB method then the corresponding download is the auto installer for a USB stick.
Once you have Memtest86 on the media you selected you'll then need to enter your bios and change the boot order so that the machine will boot from either the disk or stick you have Memtest86 on.
Try and run the test overnight if possible unless it becomes clear that there is a issue. If there is a problem with the RAM you'll see the errors pop up in red so you can't miss them.

Post any new dump files
