Helios 300 PH 315-52 Accidentally Uninstalled NVIDIA GPU from Device Manager/How to Get it Back?

So recently, about a week ago, my computer (Acer Predator Helios 300 PH 315-52) blue screened because of RAM overload (not anything GPU related, and my RAM is fine. I tried to open a game that used more than my max RAM). But, I realized that after that, my NVIDIA RTX 2060 GPU was hidden in device manager, not being utilized. I tried to watch tutorials on how to reinstate it, and one of the tutorials said to uninstall and reinstall it, so I uninstalled it. However, the issue is, I can't reinstall it, nor does it reappear after restarting my PC. I have also tried the following methods:

- Changing to Windows 11
- Restarting/shutting down my PC
- DxDiag, BIOS mode (I don't have any idea what to do there though)
- Tried reinstalling the driver, met by this prompt (I'm using windows 10 right now)

I also found this error message too which I found related to the GPU:

I don't know how to fix this. Could anyone please help? Much appreciated! (I don't think this is a hardware issue/GPU failing)

Uninstalling and restarting only works for drivers like Wi-Fi, Bluetooth, and audio, not for GPU drivers. Don't worry; follow the steps below one by one:

Ensure Windows is completely updated.
After updating Windows, cleanly reinstall the NVIDIA GPU driver using the DDU uninstaller. Follow step 8 from the guide below.

Note: Ignore the Intel GPU; focus solely on the NVIDIA GPU. Do not make any changes to the Intel GPU.

I followed everything step by step, but it says "No graphics driver found". I went into safe mode as well, clicked on the correct GPU. At least my windows is fully updated, but I do not know why it gives me this prompt. (I still don't see my NVIDIA drivers in device manager, not even hidden sadly)

Hi, download DDU freeware from the Wagnardsoft site and boot to Safe Mode in Windows hold down the Shift key and click on Restart (Power icon taskbar), select Restart with F4 (Safe Mode) from the Advanced Troubleshoot menu. Uninstall the Nvidia GPU driver with DDU and just reboot, Windows will reinstall the correct driver: https://www.intel.com/content/www/us/en/support/articles/000091878/graphics.html

Yes, You should select GPU, Nvidia gpu then click on clean aand Restart.

I've tried to install it via Wagnardsoft this time and followed the exact steps, one by one (besides manually putting my computer in safe mode via msconfig). I also redownloaded the driver download. However, it still doesn't work, and says, "This graphics driver could not find compatible hardware". I don't know why it still does not detect my GPU. :\

So when you boot into safe mode did you revert back settings before uninstall gpu driver using ddu uninstaller. Make sure your are installing gpu driver in normal mode not in safe mode. If that doesn't work, Visit acer support page and try to install nvidia VGA driver for your laptop.

Unfortunately, I tried using restore points, and I did try to install the GPU driver in normal mode. It still does not detect my GPU, but I thank you for trying to help if there isn't another option than to contact acer support
