Greetings to everyone

I had to restart the PC from Windows 10 (Software Update – no update for Windows 11).
When nothing had happened even after 30 minutes, I took a closer look at the matter. (fans were still spinning, but all in/output was gone)
on menu. The DRAM Status LED appeared on and off every 5 seconds. The CPU LED flashes briefly.

(I have been using this PC for 3 years without any major problems)

3. What are the steps you have already taken/tried to resolve this issue and what did it do?

So far I’ve replaced the mainboard battery and tried different RAM slots in pairs…unfortunately without success. Of course, even doing a manual reboot with the power button didn’t help.

Thanks in advance for the help.
