BSOD mostly occuring when playing Borderlands 2 or League of Legends

That's a good sign . Anymore errors since then ?

Members here could only advise you to do things . If you get any more BSODs just upload them .

Hi,
Yes please remove ESET as suggested in #20
Then install whichever AV program you decided on, update and run a full system scan.

STOP 0x0000007E: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED
Usual causes: Insufficient disk space, Device driver, Video card, BIOS, Breakpoint with no debugger attached, Hardware incompatibility, Faulty system service, Memory, 3rd party remote control,

The latest crash blames your Graphics drivers:

Code:

 
Driver: nvlddmkm.sys 
Dated: Fri Jun 21 10:06:16 2013
Refers to: Nividia Video drivers

As you have the latest driver installed, please follow this tutorial and roll back your
driver to the previous version:

Also you will have to disable the Nividia Update program or else it will
just install the latest driver again at some point and you will crash again.

If you carry out the following, it will also disable the Nvidia Updater and free the start up:

Free up the startup/Disable Startup Programs:

Click on the Start button
Type msconfig, click the resulting link.
It will open the System Configuration window.
Select the “Startup” tab.
Deselect all items other than the antivirus.
Apply > OK
Click the "Services" tab, click the "Hide All Microsoft Services" box, then click Disable All.
Click OK, then restart the computer.

I also noticed this driver, it is installed twice and needs uninstalled:

aoddriver4.1 C:\program files\system32\atitechnoligies\ati.ace\fuel\amd64\aoddriver2.sys
aoddriver4.2 C:\program files (x86)\gigabyte\et6\amd64\aoddriver2.sys

Code:

 
Driver: AODDriver2.sys
Refers to: AMD Overdrive; also in EasyTune6 for Gigabyte motherboard 
Known BSOD issues in Win7

Support: Raid. Frag. Dominate your games. | GAME.AMD.COM

To uninstall use:

Revo Uninstaller

Download and install Revo Uninstaller free from here: Download Revo Uninstaller Freeware - Free and Full Download - Uninstall software, remove programs, solve uninstall problems

Opt for "Advanced Mode" and uninstall the software (also delete the leftover registry entries).

These are the programs your looking to uninstall if present on the system,
the first 2 are:

AMD Catalyst Software
Easytunes
