Question PC keeps restarting to a black screen with no input on the keyboard and mouse.

[ZRubberDucky]

Hello, my PC keeps restarting to a black screen with no response from the keyboard and mouse, although all the fans are spinning. Sometimes, it only restarts 1-3 times. Yesterday, it restarted 14 times. Sometimes, when I manually restart, the PC will restart to a black screen.

Here is the list of benchmarks I have conducted, but it still keeps restarting to a black screen.

• I tried the built-in Windows 10 memory checker mdsched.exe, but no memory problems were found based on the scan results.
• Swap the RAM using a different RAM slot.
• Benchmark the GPU using Furmark (1920x1080 Fullscreen, Anti-Aliasing 8x MSAA) & Heaven Benchmark (30 minutes total), PC did not restart when the benchmark was ongoing. For Furmark, the GPU state was at 100% and 60-65°.
• Build the PC again (Pulling the Motherboard, GPU, PSU) and re-do the cable management.
• Reinstalling the Windows 10 Operating System.
• Changing SSD of Windows Operating System.
• Changing USB slot of mouse & keyboard.
• Resetting the BIOS and clearing the CMOS.

Reliability Monitor is no help. Just getting a critical event with a summary of "Windows was not properly shutdown."

PC Specs (Both CPU and GPU at idle are at 45°)
Processor: Ryzen 5 5600g (APU is disabled in the BIOS)
GPU: Asus RTX 3060Ti 8gb
Motherboard: Aorus GA-AX370-Gaming k7 (BIOS is F51i)
RAM: 16gb 8x2 2666mhz
PSU: Seasonic S12II 620W 80+ Bronze
Keyboard: Logitech G512
Mouse: Logitech G502

I haven't tried to do yet:

• Try a different RAM or use only 1 RAM stick.
• Using the PC with just the APU of Ryzen 5 5600g.
  
• Try a different keyboard and mouse.
• Try a different monitor or HDMI cable.
• Try a different GPU (Though I don't have any spare GPU)

Your help is much appreciated.

Actually that is a "help". Shutdowns occur when power is lost.

How old is that Seasonic PSU? May be at or nearing its' designed in EOL (End of Life).

If possible swap in another known working PSU using only the cables that come with that PSU.

Try to add wattage: my thought is at least 700 watts. More watts will not hurt....

You can also look in Event Viewer for other error codes etc.. Event Viewer requires more time and effort to navigate and understand.

Hi, thank you for your response. I believe the error I received in Reliability Monitor, stating that Windows was not properly shut down, occurred because when my screen restarts to a black screen, I am unable to force restart the PC. The only way I can turn off my PC is to shut down the UPS, which is then recorded in Reliability Monitor as a not properly shutdown.

My PSU is pretty old. I think it is 6 years old now. BTW, I am using PSU Sleeves (24 pins, 8 pins and 6+2 pins). I will take note of what you said about using a different PSU. Thank you!

Later I will check the Event Viewer and get back to you. Thank you so much!
