Sometimes when I turn on my PC, the screen doesn't show.

My PC spec
Intel i9-12900K
ASUS Strix Z690-i(2204 BIOS)
Intel Arc A770 LE(31.0.101.4091)
Windows 11(22623.1250)

Sometimes when I turn on my PC, the screen doesn't show. The screen turns gray and the keyboard and mouse lights up, but nothing comes up including the bios screen.
I have to do a forced reboot because the Windows boot sound is heard and the screen is not displayed even if I continue to wait.

Also, the screen sometimes turns black and comes back while using the computer.

Only obvious thing to come to mind is what is your power supply size?

That should be ok. If monitor is hanging off Arc card and this keeps happening, then you may want to get it replaced. If you are within the allowance from the storefront where you purchased it, you can have then replace it. Otherwise, you need to contact Intel directly (not here) in order to have it replaced under RMA.

Hope this helps,

Hello ResonantLake

 

If I may jump into the conversation, I understand that you are experiencing issues with your monitor turning off and not displaying anything. I would like to add the following:

 

  • Have you confirmed if the issue is present when you use the Integrated GPU?
  • You mentioned having the Windows 11 build 22623; this is a beta version. Could you try running the latest production build, 22621? This would help us discard the possibility the issue is being caused by using the Operating System's beta version.
  • Make sure the issue is present when using another cable or using a different video output.
  • Is the issue present when using a different monitor?

 

Best regards,

  • I used iGPU until 4 months ago, but there was no problem at all. 
  • When the problem occurred, I tried to power cycle the monitor, but it still showed a black screen.
  • I use same dual monitor(LG 27GP850), and  use different DP cable. If DP cable is a problem, the other monitor should have been displayed normally when I turned off the monitor.
  • The problem began around December 2022. I have used the A770 since its launch, but I remember there was no problem until December.

Hello ResonantLake,

 

Thanks for your response.

 

Since you mentioned that the unit worked until December, do you remember any Software or Hardware change around this time?

 

Also, please, try installing the latest Windows production build (22H2) and let us know if the issue is still present.

 

Best regards,

I'm having two problems.

  • Sometimes when I turn on the computer, the monitor reacts, but the black screen remains, saying there is no signal.(It's an LCD, so it looks a little gray) When this problem occurs, no screen, including a boot screen and a bios screen, does not appear. However, there is a sound of Windows booting.
  • When I use a PC, the screen sometimes turns off and turned on.

I did a bios, ME update in early December. (v2204, 16.1.25.2020)

The second problem may be a problem with Windows, but the first problem does not appear to be a problem with Windows.

I want to test it with a 22H2 build of Windows, but it's hard to test because I have to initialize my computer.

If a stable version is distributed in the Windows Participant program later, I think I can test it then.

Hello ResonantLake,

 

We appreciate the information you shared.

 

We understand that you will stick to the Windows Insider version due to the effort and time it consumes to install the Operating System production version.

 

You previously mentioned that you used the iGPU for 4 months with no problem. However, as the issue appeared in December, could you try reproducing the issue using only the iGPU?

 

Also, make sure that you have installed the latest Firmware and drivers from your monitor device. Visit the LG website listing the different software upgrades for your device.

 

Best regards,

Jean O.
