Problem with starting the PC.
Confirm the front panel header links (PWR / RESET / HDD, etc.). It's simple to remove a pin there, which could stop the system from turning on.
The only alternative method to restart is by pressing a particular pin combination on the ATX port, though I doubt it would work if the motherboard is already plugged in. Edited January 24, 2023 by An0maly_76 Updated, additional details
