The motherboard seems unresponsive due to the CPU being present inside.
Received x470 gaming wifi 5 with upgraded 5900x, BIOS updated successfully. Everything functioned until the next day when the PC wouldn’t start. I performed numerous troubleshooting steps—removed graphics card, tried different PSUs, swapped CPU and fans worked—but nothing. Cleaned both CPUs carefully, removed thermal paste residue using alcohol. Referenced a forum checklist for similar issues. Any advice?
