I'm having trouble getting my computer to power on. I have an ROG STRIX B550-A Gaming Motherboard and I've done quite a bit of troubleshooting. Here's what I've tried so far: I've checked that the 24-pin ATX power cable and the 8-pin CPU power cable are securely connected. I've also made sure the AIO pump cable is connected to the CPU_FAN or AIO_PUMP header. To simplify things, I removed the rear fan and other non-essential fans. Additionally, I've disconnected the SATA drive and any other non-essential components, including the Wi-Fi card, and double-checked that the front panel connectors for the power button are aligned correctly. I even tried removing all RAM to see if the motherboard would show any signs of life, but it only showed a brief flicker before shutting down again. I'm considering checking the power supply next and possibly trying a different outlet or cable. Does anyone have any thoughts on what might be wrong?

It sounds like you've done a lot already! One thing to consider is whether the CPU is properly installed. If it’s not seated correctly, that could definitely prevent the system from powering on.
What about checking your power outlet and the power cable itself? Sometimes the issue lies there, so trying a different outlet or switching out the cable could help.
Have you made sure that the switch on your power supply unit (PSU) is in the ON position? Sometimes it's just a simple toggle that can be overlooked.
