Solved BSOD when playing games/videos , error 0x0000003b, 0x00000050

[Kollomiser]

Specifically BSoDed twice in 1 day, once when alt-tabbing from Dota 2, and the other when playing Wakfu. Chrome was active during both instances. I am not certain about the older crashes and I think that the last two are not connected to the others.

BlueScreenView gives the bug string for the 2 latest crashes as PAGE_FAULT_IN_NONPAGED_AREA and SYSTEM_SERVICE_EXCEPTION

Majority of the crashes point to ntoskrnl.exe in BlueScreenView, but I have heard that it is not the actual culprit in most cases.

So far I have run Memtest with no errors, passed a HDD scan, also Furmark and Video Memory Test have run with no problems. I'm not sure how to pinpoint the problem further or even whether it is hardware or software issue. However, I have not attempted to run any games since the BSoDs appeared.

I did update the Nvidia drivers with GeForce Experience and Msi/Intel drivers using LiveUpdate 5 after the earlier BSoD on the 28th as other BSoD threads said to ensure that all your drivers are updated. Daemontools Light and Alcohol 52% have been uninstalled since the 28th BSoD as well.

No device is overclocked.

Desktop specs are as follows:

MB: Z77A-G43 (MS-7758) (MSI)
CPU: Intel Core i5-3470 CPU @ 3.20GHz
GPU: Nvidia GeForce GTX 650 Ti
Memory: 8.00 GB RAM (Corsair brand)
Hard Disk: Hitachi HDS721010CLA630
OS: Windows 7 Ultimate x64
Antivirus: Windows Defender

Attached is the SF Diagnostic Tool zip.

I'm stumped as to the causes and how to solve it, and help would be greatly appreciated.
Thank you very much for your time and consideration.

I recommend formatting the disk and installing a genuine Windows 7 installation. Counterfeit installations are notoriosly difficult to diagnose because they behave in unexpected ways due to the heavily modified code they contain, and many analysts will not even attempt it.
