Geforce 940m is failing at multiple games

[yeahbuddy28]

I have a HP Envy Laptop 17.3 inch with an I7 5500 and 940m. I've tried updating the drivers but they say they don't need to be even thought they haven't been updated in like 6 months. When the setting the Geforce experience program to optimize rocket league it crashes. Without this setting the game works fine but goes to black screen when i try to do split-screen. Other games (that are sometimes even easier to run) simply don't work like Battleblock Theater. As I try to download and play more games in my steam library I am finding more games that don't work even though these work fine on my AMD desktop. (also im on windows 10)

Like with tower based systems.

Laptops are prone to dust buildup and situations of where the thermal cooling solutions on the cpu and the Gpu card fitted become blocked with the dust build up.

The dust will normally collect from the enclosed flat low profile fans used to cool both the cpu and the Gpu.
Along the inside edge of the heat pipe with soldered aluminium fins that are both on the outer edge of the laptops internal casing where the vent holes are on the exterior laptop casing.

If you remove the main large back plate on the underside of the laptop.
For inspection, and service you will see the two fans talked about.

Each fan will be held in place by three screws.
Remove them, and disconnect the power from the plug connected to the laptop motherboard.
It should lift out.
Where you will see the inner edge of the cooling heat sink for the cpu or Gpu of the laptop.
If you see a thick matte of dust running along it after removing the fan.
Simply brush it away with a small clean paint brush.

Then attach the fan unit back to the laptop with the screws, making sure you re connect the power for the fan back to the motherboard of the laptop.

Your 940m card is likey getting too hot due to a lack of air flow through the fins of the cooler from the fans due to a thick matte of dust stopping the air flow.

If your laptop is a year old or even more it is worth checking.

As it is often why when you try to run a game with a mobile solution such as a 940m chip.
It produces and error, the game crashes, or you are met with a black screen a couple of seconds after launching the game title.

Or the screen goes black on you, and you are dumped back to the windows desktop.
It is as said, a sign that the Gpu chip is getting too hot due to blocked cooling solutions because of dust build up.

A quick test is to put your finger to the side vents on the external case and see how much air flow you can feel.
If it seems weak, its blocked, or partly blocked with dust internally between the fan and the inner edge of the cooling fins of the cooling solution ok.

If you have graphics or driver issues, one of the most common fixes is a clean uninstall and removal of your graphics drivers.

To uninstall your drivers, first download and run Display Driver Uninstaller, and follow it's recommendations of booting into safe mode and ect.
(This is a direct download link so you don't grab the wrong version)
http://www.guru3d.com/files-get/display-driver-uninstaller-download,20.html

You'll download a compressed file called "[Guru3D.com]-DDU.zip"
Right click and choose extract.
Go into the folder and run the DDU v##.##.exe
This will extract more files to this folder.
Run Display Driver Uninstaller.exe
Choose Yes when it asks you to boot into SafeMode.
After you've rebooted into safe mode.
When DDU comes up, if it hasn't selected your GPU manufacturer (Nvidia/AMD/Intel) then choose it from the drop down list
Press the Clean and Restart option
If a window comes up asking to disable the Windows automatic installation of display drivers click yes.

After (or before removing the old drivers, just put the new ones on the desktop or somewhere handy) rebooting back into Windows, manually download the latest drivers from Nvidia or AMD, don't use auto detect, choose you GPU model and OS from the drop down lists.

Thank you that actually fixed everything! For rocket league I had to let geforce experience optimize the game with the now working drivers and that fixed the splitscreen problem
