X570 Aorus Pro WiFi - recently upgraded from Ryzen 7 3700X to Ryzen 7 5800X and PC won't power on.


Would this be due to a lack of a bios update for the new chipset? What is the recommended fix....install previous chip, update bios, and then install new cpu? I'm just worried that something could have been bricked due to the lack of any power. I receive a quick light to the mobo but not an indicator light or anything, just the led strip for 1 second. The PC case has the power button illuminated but thats it. Any ideas? Is this a normal thing when upgrading chips without a bios upgrade?

    Hi @MatTech

    If the BIOS has not been updated since purchasing the motherboard, that is probably where I would start.

    Luckily, you shouldn't need to swap CPUs for this. Here's Gigabyte's guide on using QFlash:

    Be very careful to make sure that you do not lose power when you are updating your BIOS.

    I would also recommend that all your PSU cables are connected to the motherboard properly. I'd specifically make sure that your CPU 8-pin and your Motherboard 24-pin are connected tightly.

    Let us know if this works for you!
