Hey everyone, I need some help with a weird problem I've run into after upgrading my CPU. Here's the rundown: I have a Gigabyte B660M DS3H AX DDR4 motherboard and I replaced my old Intel Core i3-12100F with a new Intel Core i5-13400F. The system boots fine with the i3, but when I switch to the i5, nothing happens—no POST at all. The fans start spinning, the CPU cooler revs up for a moment, then slows down, and there's no display on my monitor or power to the keyboard. It feels like the system is completely stuck before reaching POST.
I've already tried a bunch of things:
- Updated the BIOS to the latest version (F34)
- Cleared CMOS by removing the battery for about 15 minutes
- Loaded optimized BIOS defaults
- Reseated the CPU
- Reinstalled the RAM
- Booted with just one stick of RAM in slot A2
- Checked all power cables thoroughly
- Disabled the VMD controller in the BIOS
Interestingly, the old CPU still works perfectly after all these efforts. Also, I had issues with my RX 9070 not being recognized until I updated the BIOS in the past. Now I'm wondering whether this could be a compatibility issue with the new CPU or if it might be defective. Any thoughts or suggestions?

You might want to try reflashing the BIOS just to be sure. Also, check if any of the LEDs or QLED indicators are showing where the boot sequence is getting stuck; that could give you a clue.
Have you counted up the power needs of all your components? The i5 draws almost three times the power of the i3, so your PSU could be overworked. What wattage is your power supply?
Why did you disable VMD? It’s noted that the Intel VMD driver needs to be updated to version 19.5 for 13th gen CPUs to work correctly. Maybe put the i3 back in, update the VMD driver from the Gigabyte website, enable it in the BIOS, and then see if the i5 will boot.
I have a 750W PSU.
