Hello, I'm facing a problem where my PC fails to boot after losing power. It displays the ASRock screen and shows the error code A2: "can't find boot device." Usually, clearing the CMOS resolves it, but today there was a power outage and nothing seems to work. I'm looking for solutions to get it running again and long-term fixes. My system specs are: motherboard ASRock B450M Pro4, CPU Ryzen 5 5600X, GPU RX 2060 Ventus XS, 6GB RAM Corsair Vengeance 32GB at 3200MHz, 1TB Samsung 870 EVO SSD over SATA.

Are you sure your connection to the storage drive is safe?

Accessing the BIOS requires disconnecting the SSD.

You just turned it on and it started immediately, honestly I’m confused about what’s happening. It seems to shut off after about two hours before turning back on again.

Unusual actions might stem from a bad power supply unit. Would you like an alternative you can replace to check if the problem resolves? Additional factors could include loose connections, failing SSD, corrupted BIOS, and more.

I don’t have another device to try since my PSU is brand new—my previous one failed last year.
