System reboots but fails to display the VGA indicator.
Hello, I've encountered frequent PC restarts and Windows errors recently. Despite following the troubleshooting steps, the problem persists. When I power on the system using one of the RAM sticks in slot A2 (the recommended slot for MSI B550-A Pro), it displays a constant CPU LED. With the other stick, it switches the CPU LED on and off rapidly, then turns off completely without any VGA light. I reset the CMOS, reinserted the GPU, and confirmed the monitor functions properly. PC specifications are included in the attached images, showing two videos of these issues with each RAM stick. EDIT: The PC operated smoothly for over three months without any problems.

According to this guide, if the lights aren't steady it means something is wrong. Other than checking the GPU, it looks like you've tried everything else.
I've successfully started the system, but it doesn't react to any key inputs. Does this indicate the GPU is still non-functional? (Attached image) EDIT: Successfully accessed BIOS after several attempts...
