Let's give something a try shall we?

Download the attached program and run it according to what you see in the picture, you can disregard going into safe mode because you have no driver in use at the moment and for the same reason rebooting isn't mandatory either.



After the program is done, try the following driver package: https://www.nvidia.com/download/driverResults.aspx/162103/en-us

It's a standard driver instead of a DCH one, it may be worthy to give those a try in case your system doesn't play along with DCH for some reason. If they fail, give DCH a try: https://www.nvidia.com/download/driverResults.aspx/162106/en-us

Report back with whatever happens please.

not working bro, tried with both of your suggested drivers

Huh... could there be something wrong with your hardware then?

When did you start experiencing this?

I noticed this thing 15-20 days before tried so many things but nothing worked

I assume you went through a clean Windows installation right?

If you didn't it may be worth trying, in case you need it I wrote a thread about it yesterday: https://community.acer.com/en/discussion/607771/guide-how-to-install-windows-10-cleanly#latest

If you go through it, let Windows Update be the one installing the driver for the graphics card. You can always update it later on, but it's good to have some sanity on how the environment is.

i tried that too recently , after this issue

That's too bad, I'm afraid I'm out of ideas then, servicing the laptop seems to be the only solution

Yeah tried that too😢 but they are giving just excuses I'm from a village and not reachable for them because of this pandemic. But thanks for your efforts really appreciated

Darn, that's too bad, I hope it ends up working again for what is worth.

There's nothing to disconnect and reconnect inside the laptop because the graphics card is soldered...

I'm out now, but I have an idea. I'll write later on, we can try to see if it works in Linux.

I'm sorry for the delay, the operation and getting a way for you to replicate it there proved difficult (but now it's easy).

Things you'll need:

• An USB stick, 16GB+, I'm afraid 8GB won't do.
• Downloading an image I made of the Linux installation for my machine, which should be close enough in regards to the graphics card at least (it's an MX250). Because a live DVD wouldn't work for what we needed and I wanted something that worked on a different machine without too much troubleshooting I went for Linux Mint.
  
  I compressed the image (it was ~14GB) and archived it in 2 parts for easier downloading, these are the links: Part 1 & Part 2.
  
  
• OSForensics' ImageUSB, it's the software we'll use to write that image to the stick.
• Secure Boot disabled in the firmware settings, I don't think this Linux installation would like it.

Here we go:

1. After downloading both parts of the image, double click the self extracting one and choose where you want it placed, it's 14.3GB in size. The resulting file is called MX150.bin.
2. Insert the USB stick and remove anything you want to save from it, its contents will be overwritten.
3. Open ImageUSB and select things carefully, in the top part you have to choose the stick. Use this image for reference:
   
   
   
   
4. After clicking Write you'll be presented with a couple of screens so you double check the disk you selected and then the process will begin. You can safely disregard the warning about having less space afterwards in the USB stick, it's because what I used was a 16GB stick and if you use anything bigger the partition table will be trimmed to 16GB, but as soon as we clean it later on you'll have it as it was.
   
   Also, writing can be slow if the drive is USB 2.0, but it'll get you there.
   
   If you see the following dialog after the process is complete telling you to format the drive, click cancel, we don't need to (and it'd actually undo the writing haha):
   
   
   
   
5. With the stick inserted, boot into it. You'll need to be in UEFI mode and with the boot menu enabled (that F12), drop by the firmware settings when booting (F2) in case those aren't the settings you have. In the boot menu you'll see "ubuntu", that's the one we're looking for.
6. After it has finished booting (it can take a while too if the stick is slow) you'll be at a desktop already. Not too unfamiliar, there'd be a start menu of sorts and Firefox is installed should you need Internet (the default search engine seems to be Yahoo though). There's an icon for network connectivity next to the clock, just in case.
7. If you weren't able to reach here, there may be a problem with the graphics card. I have configured it to use the MX150 directly and not any integrated Intel card. I have also set it up so the official NVIDIA 440 drivers are in use instead of nouveau.
8. I left a shortcut to the NVIDIA settings app in the desktop, double click it and post some screenshots if possible (Alt+Prnt Scr shows a nice dialog to save it after you release both keys ). For example, this is my MX250:
   
   
   
   
   
   
   
   You can then close the program.
9. I left another app to test the graphics card, it's inside the "Unigine_Valley-1.0" folder in the desktop. Open that folder and double click "valley", you'll be asked if you want to run the file and some other options, choose the right most one, "Run":
   
   
   
   
   
   
10. The default settings are OK, click on RUN> and let's see how it goes, you should see some 3D rendering and in the top right mention to the MX150 and how it's doing. Exit by using Esc for example or navigating with the mouse.

That's it, give it a try and please report back, if everything works as I have described it I would consider there's no problem with the graphics card and something is up in Windows. At which point I would just go through another clean install (following the steps I detailed earlier in that guide). If there's no output, etc. etc. I'm afraid it's a hardware fault and something we can't fix ourself

By the way, if you're ever asked for a password, it's "testing".
