Computer won't boot

[InitiateSleep]

Hello, recently I have been experiencing an issue where if my PC loses power it doesn't boot, it gets to the ASRock screen and the code it gives me is A2 which is "can't find boot device" I believe, usually I can fix it by clearing the cmos but I had a power cut today (I know I need a ups) and nothing I do seems to get it to go. Any ideas on what can get me up and running and what can fix it in the long term?

 

Specs:

Mb: ASRock b450m pro4 

Cpu: Ryzen 5 5600x

Gpu: Rtx 2060 ventus XS 6gb

Ram: Corsair vengeance 32gb 3200mhz 

Ssd: Samsung 870 Evo 1tb sata

I can't get into bios unless I unplug my SSD.

I just press the power button and it fired right up, I really don't know what's going on lol, it'll stop working for like 2 hours then will just work.

Strange behavior can sometimes be caused by a faulty PSU. Do you have another one you can swap to see if the issue goes away ?

Other parts that may be causing that issue are loose connectors, your SSD dying, corrupted BIOS and a few others.

I do not have another to test with, however my psu is very new because my last one died last year
