1= no system doe snot reboot.

2= Intel CPU and GPU is AS Rock. they claimit is a known issue from you and the A770

3= CoolerMaster 1200 Watt psu.

 

 

responce to following quesitons.

Thank you for posting in our communities.

 

I have some questions, just to clarify a few details about this issue:

  1. When you say "black screen", do you mean the system turns on but there is no video at all? Or is it that you see a video display during the POST sequence and the black screen occurs once Windows loads?.
  2. Is your GPU Intel-branded, or is it from a different vendor?
  3. What is the make and model of your power supply? This is just to rule out an issue with power delivery to the GPU.

 

From the SSU you provided, I saw the integrated graphics are enabled as well. Have you tested by disabling the iGfx from the BIOS? (This is just in the odd scenario of a conflict between GPU switching.)

 

We look forward to your response!

 

Thank you, and have a great day ahead!

Hello Mikewic,


Thank you so much for patiently waiting on our response.

 

Please perform the following steps in order for us to narrow down the cause of the issue: 


1. If it is feasible, please attempt to connect to an alternative monitor, preferably one with a lower refresh rate and screen resolution.

2. Consider reducing the screen resolution settings on the KoorUI 27" Gaming Monitor. (For thorough documentation, specify the screen resolution that is being used.)

3. Similarly, try decreasing the refresh rate settings on the KoorUI 27" Gaming Monitor.

4. Check whether HDR is activated. If it is, please try disabling it to see if this impacts the issue.

5. Ensure that the graphics driver is updated to the latest version, which is 31.0.101.5445, and observe if there are any improvements.

 

Please let us know the results once you have already performed the steps that we have provided.

 

Thank you, and have a great day ahead!

Hello Mikewic,

 

To better understand the situation and assist you effectively, we kindly request the following information and actions regarding the black screen issue you've encountered:

 

1. Could you please provide the make and model of the monitors you are currently using?

2. Does this issue persist when you connect through the HDMI port on your graphics card?

3. Have you had a chance to test the system with only one monitor connected? If so, does the black screen occur in this setup as well?

4. When the black screen appears, could you note which applications are active? This is to determine if the issue is triggered by having multiple applications open simultaneously.

5. For diagnostic purposes, could you try using a single monitor connected to the DisplayPort (DP) on your graphics card and observe if the issue reoccurs?

6.  Lastly, I recommend performing a DDU to completely remove the current graphics drivers and then checking for any improvements.

 

 

Best regards,

Carmona A.

I solved the problem. It originated from installing Windows with a different GPU and then switching to A770. I removed every drive and reinstalled Windows 11 on a different drive with the A770 as primary display and it has worked flawlessly since. In BIOS/UEFI setup I chose auto for GPU selection and no secondary display (but the OS still lists both internal graphics and the A770 in Device Manager).

 

Then I reattached the previous drives including my previous boot drive.

 

To boot my previous system I added a BCD boot entry to the disk I recently installed Windows 11 on. (Easily done with a graphical BCD editor tool or through command line. ) That way it uses the recently installed EFI partition on the new drive but booting my previous drive that I had problems with. 

 

Do not choose the previous Win11 installation as boot drive in BIOS/UEFI setup as that will use the faulty EFI partition.

 

Does this solve your problems? (This is not a problem with the A770. It is a EFI partition configuration problem.)

 

David
