Question Computer wont boot after upgrading to a new CPU

[ConfusedBonobo]

I successfully updated my bios to the latest vios version (f11d) then after swapped my i3 12100f for the i5 13600k and it would get stuck on CPU led and my case power button led would be flashing. I swapped back to the i3 and it worked then swapped back to try get the i5 to work however same problem.

Specs:
b760 ds3h ax ddr4 motherboard, i5 13600k cpu , 4x8gb 3200mhz ram, 650w PSU, rtx 3070

Did you clear the CMOS after verifying your BIOS was flashed to the latest version? How are you cooling the processor? Make and model of your PSU?

I cleared cmos after installing i5. cooling the cpu with aluminum heat sink tower and fan.
PSU: corsair vs 650w 80 plus white
