Random BSOD Windows 7

Hi,
i have problem with random bsod, they usualy appear while playing games or watching tv.

Things i tried:
- reinstalling system on different hard disk
- reinstalling graphics drivers
- updating bios
- increasing cpu voltage ( from 1.2V to 1.3V)
- changing windows power managment options

Memtest after 12hours was clean.

minidumps and everest pc report attached.

I would be gratefull for any help:>

Edit:
added some reports

Hi and welcome to SF friend!

Here are several things:
First of all, L1E62x64.sys was blamed in the dmp file. It is your Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controller (NDIS6.20). Please download and install fresh copy of it.

nvlddmkm.sys was blamed. It is your nVidia Video drivers. When upgrading your graphic driver you MUST remove all traces of the current driver. In order to do that we recommend using Guru3D - Driver Sweeper

When it is removed then download and install the fresh copy.

Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Boot from the CD, and leave it running for at least 5 or 6 passes.

Do you have another graphic card that you can try on your system (borrow?)

Run system file check:

Open an elevated command prompt and enter sfc /scannow.

Let us know if you need help

When did you do the memtest? What memtest? You gotta use memtestx86. 8 pass should take at least 8 or 9 hours my friend. Please use memtestx86 and test your Ram whenever you have time. That's critically important.

Tuan

Sorry the problem hasn't gone away. nvlddmkm.sys, your Nvidia graphic card driver is faulty and cause memory corruption. When upgrading your graphic driver you MUST remove all traces of the current driver. In order to do that we recommend using Guru3D - Driver Sweeper

When it is removed then download and install the fresh copy.

It can be driver or the device faulty. Let's reinstall the driver again.

Run this free video stress test:
Try this free video stress test: FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net

FurMark Setup:
- If you have more than one GPU, select Multi-GPU during setup
- In the Run mode box, select "Stability Test" and "Log GPU Temperature"
Click "Go" to start the test
- Run the test until the GPU temperature maxes out - or until you start having problems (whichever comes first).
- Click "Quit" to exit
