When using Nvidia GPU shoiuld I disable mobo onboard graphics?

The integrated graphics should be disabled as default when using a dedicated gpu connected via a source of its I/o. There shouldn't be a need to disable it in the BIOS. You can try to completely start fresh with your graphics driver for troubleshooting if nothing else works. This will wipe your Nvidia driver completely and will let you start over.

1. Download the latest Nvidia driver here: Drivers | GeForce
2. Download DDU here: Display Driver Uninstaller (DDU) V18.0.0.6 Released. *updated* - Wagnardsoft Forum

3. Extract and install DDU
4. Disable your internet connection (important!)
5. Boot up Windows in Safe Mode: https://support.microsoft.com/en-us/...c-in-safe-mode
6. Run DDU and choose your graphics vendor, click Nvidia and select Clean and Restart
___________________________
7. Once the PC has restarted to WIndows proper, run the .exe driver you downloaded from Nvidia and go through the install process.
8. Click custom installation (not express) and check mark the clean install option. Make sure you check mark Geforce Experience aswell as other drivers you want in this process.
9. Restart and connect to the internet.

Edit; Me and my slow writing.

Just a note for the OP....

The Java it required you to download and install is for the detection software to run on your machine, no bearing on the driver at all.

Second, easiest way to disable the onboard GPU is thru Device Manager. Right click the device, and click disable and follow thru. Example:



And...... best way to install the NVidia driver is as posted by both Grom0X and Faith above!

But...
If it's not disabled in BIOS, doesn't the motherboard reserve memory for it still?
Also it it's still enabled in BIOS the (probably) two iGPU VRMs feed iGPU volts too, which warms up the CPU and the iGPU's VRMs for no reason. or am I wrong?

Cliff, I have no idea! Wondering, though, if it's disabled in BIOS, what does Boot use to talk to you? And what happens if the NVidia croaks? Stevie Wonder graphics?

And the DDU uninstall....what does it use after restart? Before the NVidia driver is manually installed?

Clear CMOS(BIOS Reset)?

That'll do it! Still think it's easier to disable in Device Manager. Although I don't think that's his base issue. Not when the problem travels to a new box. Just IMO...........

Actually having both iGPU and dGPU turned on at the same time should not cause any problems at all.

Maybe the wrong JAVA version, needs JAVA RE version 8: Download Free Java Software
Not JDK/JSE.
