[Help] Lenovo G470 video card problem.

Hello guys, I try to be detailed as possible in this problem.

 

While watching a H264 MKV AAC video using mpv using this parameters:

mpv --vo=opengl-hq:lscale=lanczos3:cscale=lanczos3:dither-depth=auto

 

my computer suddenly blue screen with this dump. [download here : http://1drv.ms/1ujkdR4], summary detail of BSOD(Nirsoft BlueScreenView):

 

-- SOF OF BSOD --

A problem has been detected and Windows has been shut down to prevent damage
to your computer.

 

The problem seems to be caused by the following file: atikmpag.sys

SYSTEM_THREAD_EXCEPTION_NOT_HANDLED

 

If this is the first time you've seen this stop error screen,
restart your computer. If this screen appears again, follow
these steps:

 

Check to make sure any new hardware or software is properly installed.
If this is a new installation, ask your hardware or software manufacturer
for any Windows updates you might need.

If problems continue, disable or remove any newly installed hardware
or software. Disable BIOS memory options such as caching or shadowing.
If you need to use safe mode to remove or disable components, restart
your computer, press F8 to select Advanced Startup Options, and then
select Safe Mode.

I tried to UNINSTALLALLGRAPHICSDRIVER.jpg (incude Intel graphics driver) and reinstall them (first the intel graphics driver: Intel Onboard Graphics Driver for Windows 7 (64-bit) - Lenovo G470 and G570) and the problem still exist.

 

I tried to manually update the driver using the *.inf file and it failed.
