Question Pc powers on then shuts off right way.

My other post I just made

I just bought a different PSU and it didn’t work. Like I said before the EZ-DEBUG ones on only for the CPU and it doesn’t go past that. It’s does boot all the way. Just lights up and shuts down after 4 seconds. Need help

Did you plug in the 4 or 8 pin CPU power connector? Are you sure it's secure? If not that might cause CPU errors on power up.

Everything is plugged in and I double checked to make sure everything was secured

Have you updated your BIOS, one of your old threads says you bought a 3600 for an older B450 board. If you did you have to do the BIOS update to get the system to boot, the board cannot recognize the CPU without the correct BIOS.

Turns out it was bc the pc case I was using didn’t have a reset button connector for the front panel pins. I put it into a different case and it now boots but doesn’t post. I’m starting to defidently think it’s a bios update issue but I’m not getting mg the flash bios to work. It just flashes for 4/5 flashes and then stops. Everything seems to be working except for it not posting
