Hello,

Thank you for having me in your community,
This is my first thread as i seek your help,

I have an Asus N55SF laptop,
i have a problem with the intel graphic(i think, well that's what i found out so far),
the screen always gets black (with some liltle white dots on the left side of the screen),
And when i gently hit the pc (on the left side to be specific where the logos on windows and intel are),
sometimes the screen gets back to normal, and sometimes i have to hit harder.
Now when i open a game(dota2 for example) or anything that uses the nVidia graphic cards, this problem cease to happen, even when i let it run on the background i dont get this problem.
When i plug the pc (using HDMI or VGA) to an external monitor(datashow or TV), the screen of the pc gets black,
but the external monitor dosnt.
So i concluded that this is all the intel HD graphic fault.

So is turning off/disabling the intel graphic card, and force the pc to using the nVidia card instead all the time would fix this(i dont care about how much energy it take, the battery dosnt work anymore anyways).

I tried to disable it from the "Device Manager" (i'm using windows 8.1), i get a warning, and when i press ok the screen goes black and i cant do anything to restore it.
I also tried to go to BIOS, but i couldnt find any option related to the graphic card,
here s what i have in BIOS:

One more thing, is the intel HD graphic is on it's own chip (its own card) or it is "in" the CPU itself, cause i tried to find it on my motherboard, but couldnt.

Thank you, and i appreciate your help, this is really important to me, cause hitting ur pc to restore the picture is really embarrassing specially in front of other people.

Yes.
Good job in taking it apart. Clean and tighten everything to see if it helps.
Also, you can try to clean the CPU / GPU heatsink, but only if you are confident enough. Also, if you had experienced high temperatures recently, you can try to reapply some thermal paste, but again, if you are confident enough.

Do not disable the Intel HD graphics from the device manager, it will kill your system.
Just go to the Nvidia Control Panel -> Manage 3d settings -> Global Settings -> Preferred graphics processor - Choose Nvidia.
Restart and only the Nvidia GPU will be used and the Intel one will remain deactivated.
Also, the HD graphics is "integrated" GPU. So, you cannot see it as it is "integrated" with the cpu.
Here's a topic on "location" of the iGPU.

Hope this helps.

Thank you for your reply,
i will try that nVidia thing,
but say i want to fix this intel graphic, do i need to replace the whole chipset or what?

You cannot fix the Intel iGPU specifically. You have to change the CPU and that in an old laptop is not worth it. In any case, I have never seen the iGPU going wrong. You can try to update the driver from Intel's site and see if it helps. If not, keep using the Nvidia GPU for now. Since you don't have to worry about the battery, the Intel iGPU is of no use anyway.

So i changed the config in the Nvidia control panel, but the same problem occurs ...

That means it is most probably some connector at fault. The iGPU's as i said above rarely go wrong. Since the problem occurs with Nvidia GPU also, it is surely some loose connector. If you can, open the laptop and visually inspect for bad / loose connector. If not, take it to a service center if it is compelling enough. Else, just keep on tapping :)
