BSOD while playing videos or playing games (LoL) Error STOP : 0x00007A

[bsoddvictim]

Hello sevenforums Community,
since about month im getting Bluescreens, which never happened before in 4 years.
It usually get the when i watch streams on twitch (which didnt happen since 1 week on my account though) or currently while playing League of Legends.
But they dont come every game, so i can for example play 4 games in a row and nothing happens or i get 3 one them in one game. Also they can come at any game time. It is kind of random to me how they appear.
The last two days I got about 7 so i really need help from u guys.
In the last two weeks i always got this message (STOP : 0x00007A (0xFFFF6FC50023598,0xFFFFFFFFC000000E,0x000000002A991880,0xFFFFF8A0046B30BE) ) without a sound and the pc didnt instantly reboot.
But the last days the Blackscreen stayed like 4 second so i couldnt see the error message on it, so i dont know if the error changed but there was this buzzing sound.

I really appreciate help (and sorry for my english skills ^^)

Do you have the Atheros Network Adapter installed on your PC? If so, please update it and let us know.
The other dmp file wasn't too helpful - not sure if it was my windbg or if it was just corrupted.

Also can you run chkdsk?

I'm no BSOD expert but I do know 2 gigs of ram is not enough to do much on a Windows 7 Ultimate/64.

Where did you get your copy of Windows 7 Ultimate 64 bit?

@Layback Bear 2 GB isnt much but Win 7 Professional x64 is running since years on this laptop, which i got from my uncle. So about 2 months ago i wanted to get rid of all the unneeded files and installed Windows 7 Professional again with a iso and the Product Key which is on my laptop. So its legally bought and only ran on Win 7 Prof x64.

*Edit: I just realised u asked for Windows 7 Ultimate x64 which i dont have (sry for the false info i gave im updating it)

@carz95 Yeah i have a Atheros Network Adapter (as well as a PCI-E Ethernet Controller from Artheros) and with my last Windows Update (was around 2 days ago) both got updated but i will search for the newest version for if necessary.

And yes i ran chkdsk quite a few times (sometimes after a Bluescreen it starts automatically) and in the Event Viewer i couldnt find the chkdsk log as described in the tutorial, but the wininit log. I can post it but its in german i dont know how to change that

In case the dm log zip was corrupted here is another one :

Thanks for your help guys i really dont know what to do
