Black screen between POST and lock screen

I have recently encountered an issue, where my PC is posting, the motherboard manufacturer logo appears with a loading icon, afterwards the monitor goes black, but the signal stays, then after about 30-40 seconds it goes to the windows lock screen. Before this it just went straight to the login without the screen going black or the delay. The monitor itself is fine, I tried with a different monitor and cables, the issue was still present. I also tested it with all 3 DP ports and the HDMI port on the GPU, with the same result. Unfortunately my PC has no IGPU to test with. Windows and my GPU drivers are up-to-date and since the BIOS was from 2022 I updated it to the latest just in case, but no change. There‘s also no problem with the signal after I get to the desktop. Could this be software-related or is my GPU acting up?

Specs:

Processor: AMD Ryzen 5 5600
RAM: Kingston FURY Beast 16GB (2x8GB) DDR4 3200MHz

GPU:AMD RX 6700 10gb

Motherboard: MSI B550 A-Pro

OS version: Windows 10 22H2

    Hello, Aron Lauer

    Welcome to the Microsoft Community!

    Thank you for your feedback. I have read the information you provided. You mentioned that your computer displays the motherboard manufacturer's Logo after POST (Power On Self Test), then the monitor goes black (but the signal is still there) for about 30-40 seconds before it goes to the Windows lock screen. Prior to that, the system was going straight to the login screen with no black screen or delay.

    There are many aspects to the problem, it could be startup items and services, corrupted system files, faulty graphics card hardware or wrong BIOS settings, etc.

    I suggest you try the following methods to troubleshoot the problem step by step.

    1. Check startup items and services
    2. Press Ctrl + Shift + Esc to open Task Manager, switch to the “Startup” tab, and disable unnecessary startup items.
    3. Press Win + R, type msconfig and enter. In the “Services” tab, check “Hide all Microsoft services”, then disable all other services and restart your computer to see if the problem is solved.
    4. Repair system files
    5. Open a command prompt (as administrator), type sfc /scannow and press enter. This command will scan and repair system files.
    6. Run DISM /Online /Cleanup-Image /RestoreHealth to repair the Windows image.
    7. Enter BIOS, restore default settings, save and exit. Since each computer manufacturer has different BISO settings, you can check how to perform the reset operation on the BISO manufacturer's official website or the instruction manual.
    8. Check for hardware failure

    Although you don't have an integrated graphics card, try testing your graphics card on another computer to see if the same problem exists. If it still occurs, then your graphics card may be malfunctioning.

    I hope this information has been helpful. If you have any questions, please let me know and I'll be happy to help you further.

    Best regards
