Oh wait, now I think I understand. So you're saying the iGPU works with no driver but stops working when you install the driver, correct?

 

It looks like that GPU will only work on Windows 10.

 

Try installing this driver - https://www.amd.com/en/support/previous-drivers/apu/amd-ryzen-processors/amd-ryzen-3-desktop-processors-radeon-vega-graphics/amd-ryzen-3-2200g

Briefly: 2200g Integrated graphics drivers cause my monitor to go black (no signal) but the computer otherwise works fine. The Microsoft Basic Display Adapter works for basic stuff but not for games. Details below...

 

Thanks in advance for reading and trying to help a newbie. I really appreciate any advice.

 

Brand new build, just used 2 month

                                                                                                                                                                                                    

Details:

I am stuck with the "Microsoft Basic Display Adapter." I can update the driver in a large number of ways, but each method leads to the screen going dark.

The computer is on and responds to commands. I can shut it off with a keyboard shortcut for example.

The only way to get the screen back is to start up in safe mode. If I roll back the driver in safe mode I can then restart the computer normally.

Other than this everything seems to work fine: sound, network, monitor, peripherals.

At no point have I seen error lights on the motherboard.

 

What I've tried:

1.   Clean windows install, run windows updates first (installer starts from version 1903). Then safe mode as needed, windows update tries to install display drivers so it goes black. I then have tried installing drivers from AMD software (old and new versions) and from the MSI DVD that came with the motherboard.
2.  Clean windows install, run driver updates from AMD and MSI before I let windows update do anything.
3.   Using DDU to clear display drivers in between attempts and not using it, that is just telling windows to roll back the drivers or disable the device.
4.   BIOS updates for the motherboard. It came with a Ryzen 3rd gen compatible BIOS so I've tried with that original bios, version 3.0, as well as the latest BIOS, version 3.3.
5.   I checked the performance of the processor alone in Cinebench. It seems to perform as expected. But of course I can't check the integrated graphics because the drivers won't work.
6.   Removing 2nd ram stick and removing wifi card - made no difference
7.   Installed another 2200g processor on the off chance that there was a problem with mine. No difference, same behavior.
8.   Installing old drivers from both AMD and Windows driver repositories. Most create the same black screen. Some cause windows to be unable to startup.

edited: and new problem occurred in bios it's showing 8gb ram but in windows it's showing 3.59gb

I tried setting it from msconfin but didn't worked

 

and sorry for the trouble

 

Thanks for reading all that!

windows has had issues in a recent update. if you manually install a driver etc.. it will break the driver and it is relatively a pain to fix. I had this happen on my system, but was lucky and it was not my display driver. Try this also, https://www.techradar.com/news/new-windows-10-driver-problem-could-be-the-most-serious-yet-heres-how-to-fix-it.  I am not saying this is causing the current issue, but could have started it. I would wait for a few months  till windows patches this issue or try to update through the device manager/ windows update to avoid issues..

sidebar, Use older driver if it works for now.
