    Try windows x 
    go to device manager 
    expand display adapter
    right click on display driver - uninstall 
    Restart the computer 


    If you are not able to see the display adapter on device manager - go to view on top - click on show hidden devices.    It will showing you the display adapter which might be hidden.   Try to uninstall it and restart the computer.  


    It should work fine.. 



    If it is still not working 
    Uninstall the display adapter from device manager  ( if you are able to find it ) 
    Dont restart the computer. 
    Go to support.acer.com 
    chose your country 
    type snid or chose your model 
    go to drivers 
    Install the display driver 


    If the computer is not detecting the display adapter...


    Doing the power drain and bios defaults will really help.  Kindly follow the steps given below:


    Turn off the laptop. Disconnect or unplug the charger cable, devices or any other cables connected to your laptop. Close your laptop. Turn it upside down.  On the bottom of the laptop, you can find a  pin hole. It is a tiny hole. You can a find a battery symbol indicator next to the hole. It is like a + and - sign symbol as though somebody is trying to shift the battery out. Insert the pin on to the hole for 30 seconds. Remove the pin. Flip the laptop. Connect the charger cable, turn on the computer.  Only on laptops where the battery is inbuilt you can find the battery reset hole on the back of laptop.


    If you don’t find a pin hole on the back of laptop then you might be using removable battery. There is no need to unscrew anything to remove the battery.  Turn off the laptop. Disconnect or unplug the charger cable, devices and any other cables connected to your laptop. Close your laptop. Turn it upside down.  On the bottom of the laptop, please look at the top or bottom depending on the way you look at it. You can find a long door. It is a battery removable door.  Just below that you can find a latch.  If you move the latch you can remove the battery door. Once the battery is removed, flip the laptop. Open the top cover, press and hold the power button for 1 minute. Connect the battery back on the back of computer. Connect the charger cable back and then turn on the computer. 

     

    If you don’t see a reset pin hole on the back of laptop or if you are not able to remove the battery (if it is inbuilt) then please unplug all the cables and devices out of laptop.   Hold the power button for 1 minute.   Connect all the cables back and restart the computer.  



    While turning on the computer, tap f2. It will go to bios. Press f9 once. It will show load bios defaults with a yes or no popup. Press enter. Popup screen will disappear.  Press f10 once. It will show save changes popup with yes or no. Press enter. Computer will restart and it will load into windows.

    I am amusing by Windows X you mean Windows 10 but if I'm wrong correct me and I am on Windows 10 Home. Doing the BIOS defaults and the power drain did not help. It does not show up in device manager even if I show hidden devices it shows up no where on the computer to my knowledge.

    Press WIN+R. Enter 'msinfo32'. In the right pane, what BIOS firmware version number do you see? Is this the original factory version?

    Insyde Corp. V2.02, 1/3/2019
    I updated the BIOS to fix the problem (which did not work) so no it is not the original factory version.
    I got the updated BIOS from the official Acer website @ https://www.acer.com/ac/en/US/content/support-product/7244?b=1 and updating the BIOS went smoothly but it still did not fix the problem.

    OK. Did you check each BIOS menu tab for options (press Ctrl+S to reveal any hidden options) relating to setting the nvidia chip?

    Nothing shows up in BIOS about the NVIDIA chip and Ctrl+S doesn't seem to bring up any hidden options

    If you're sure the nvidia hardware disappeared with the factory-installed firmware, then the best way to rule in or rule out a GPU chip failure, is a full erase-everything ACER OEM factory reset using the ALT+F10 cold boot method. Pretty drastic but at this point it looks like it got fried somehow perhaps by overheating

    I suspected something similar to that. I just got it fixed because the screen was broken and they said they were gonna make sure everything was in working order but they were not very professional as it took them just short of 5 weeks just to fix the screen so I would not be surprised if they did not realize the GPU wasn't working. Can you go more in detail on how I can do a "full erase-everything ACER OEM factory reset using the ALT+F10 cold boot method"?

    OK.
    (1) First backup any personal files on a USB stick.
    (2) Then shut Windows down normally. Turn it back on and immediately start tapping the F2 key to enter the BIOS menu
    (3) Make sure the F12 and D2D options are enabled in the BIOS Main tab.
    (4) Then set and save a supervisor password in the BIOS Security tab.
    (5) Press F10 to save BIOS settings and exit. Windows should still boot again.
    (6) Shut down Windows again. Turn it back on and immediately start tapping the F2 key to enter the BIOS menu again but with the password.
    (7) Turn off secure boot in the BIOS Security tab.
    (8) Press F10 to save BIOS settings and exit. Windows should still boot the same.
    (9) Shut down Windows again. Turn it back on and immediately press and hold the ALT key while tapping the F10 key.
    (10) The ACER OEM factory reset menu should appear. Follow directions for the full erase everything reset.
    (11) Immediately after the OEM reset is complete and you're at the desktop screen, press the FN+F3 key combo to turn off networking ASAP
    (12) Then see if you can find the chip.

    That did not work either. Looks like I'm going to have to take it back to the store.

    What didn't work? The reset didn't work? Or the the reset worked but the GPU is still missing?

    The reset worked but the GPU is still missing. However, now there are 2 unknown devices in device manager. I'm not sure what exactly would be of importance to you so I am going to provide you with the Hardware IDs for these unknown devices for now.

    They're both drivers related to integrating the missing nvidia gpu device with the mainboard bus. The unknown device simply confirms that the gpu is indeed still missing.

    Good luck. I doubt they can do much unless it's a cracked solder ball which occasionally happens. Then they can try a reflow with a heat gun or toaster oven.
