Windows 7: BSOD (3x) Alt+Tab while in game (Steam)

BSOD (3x) Alt+Tab while in game (Steam)

Received three BSODs in last few minutes while using Steam, happened while playing Warface (2x) and then Besieged (1x).

First BSOD (Warface): I thought it might have been due to trying to save a video using GeForce Experience and ShadowPlay. BSOD when I used Alt+Tab.

Second BSOD (Warface): Geforce Experience was not running. BSOD when I used Alt+Tab.

Third BSOD (Besieged): Changed games to test if it was simply Warface. Don't recall if Geforce Experience was running. BSOD when I used Alt+Tab.

Thanks for your help.

Hello, Honestly welcome to the forums. I will see if I can help. All 3 of your dump files blamed your Graphics drivers.

Use !analyze -v to get detailed debugging information.
BugCheck 50, {fffffb240d0a5300, 0, fffff880049b5940, 7}
*** WARNING: Unable to verify timestamp for nvlddmkm.sys
*** ERROR: Module load completed but symbols could not be loaded for nvlddmkm.sys
Could not read faulting driver name
Probably caused by : nvlddmkm.sys ( nvlddmkm+ee940 )
Followup: MachineOwner
I would also suggest you try reinstalling the drivers using this tutorial, and install only the Graphics drivers and PhysX. GeForce experience, causes a lot of people serious problems. NVIDIA Drivers - Avoid Problems

I would also recommend you uninstall Norton as it is a well known cause of BSODs. Uninstall it, then run the Norton removal tool
Then replace it with Microsoft Security Essentials (Microsoft Security Essentials - Microsoft Windows) .

Also, if you are overclocking anything, please set everything back to default levels. Try those things and see how you do, then let us know.
