Windows 10: Dell G15 gaming laptop crashes and has 0 video memory?

Help me please fix 0 video memory on my sons Dell G15 gaming laptop ?

:)

 

"Video_dxgkrnl_fatal_error" while playing games on my Dell G3 laptop ?

So every time I play a game after like half an hour or so, my game crashes (blue screen giving the error VIDEO DXGKRNL FATAL ERROR ), then when I relaunch the laptop my discrete GPU is gone, like missing from task manager and hidden in device manager. To fix it I have to restart my laptop then the Nvidia drivers come back and when I play my games again the same problem happens after a few minutes of playing the game. It's never happened unless I'm playing a game.
I have tried:

• reinstalling the graphics driver from NVIDIA.
  
• removing the graphics driver using DDU in safe mode and reinstalling the latest one.
  
• running sfc and dism
  
  None of the above methods helped.
  My laptop is out of warranty so don't suggest I take it to the Dell service center as they will just say to replace the motherboard, I know that and that will be like buying a new laptop.
  
  My laptop is a Dell G3 15 3500

Fix for frequent crashes on a dell 2-in-1 laptop

I have a Dell Inspiron 2-in-1 laptop.

Model: Dell Inspiron 13-5378.
Processor: Intel(R) Core(TM) i7-7500 CPU @ 2.70GHz 2.90GHz
Installed Memory: 8 GB
64-bit Windows 10, x64 based processor.

It usually crashes when there is a game running. It crashes even when a GBA emulator is running. Some times the laptop can handle a game client running by itself and nothing else running. But most of the times it crashes when any game is running.

The laptop is around 6 months old. In the first couple of months it didn't crash. It hasn't been damaged in any way.

 

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?
