Question m2 slot 1 not working on new mobo

[Gilsa]

I recenly bought an msi mpg b550 gaming plus, to pair it with a ryzen 7 5800x. Also bought a new psu, the msi mag 750w. For some reason when I placed my m2 ssd on slot 1, the one with the lightining gen 2, the pc didnt get any image. But when I plugged it on slot 2, the pc works normally. Also, I cant get any hdd to power up, currently have 1 m2 ssd and one 2.5 ssd, working correctly, but for some reason the hdd doesnt power up, already tried two different ones and neither one powers up. Am I plugging the wrong cables or is just an issue with the motherboard?

m2 ssd: Samsung Evo 960 256 GB ( mz-v6e250) > Only works on m2 slot 2
HDD : Seagate 1tb 7200rpm (st1000m003) > doesnt power up
2.5 ssd: crucial 2.5 ssd 256 GB > works fine

Check your motherboard manual. Some hardware can lose functionality based on what SATA/M.2 connections are used.

Welcome to the forums, newcomer!

Which SATA port is the SATA device populating on your motherboard? As for your motherboard, what BIOS version are you on at this moment of time?

Hey, thanks, the sata m2 is currently on m2_slot 2, the 2.5 ssd is on port 4. As for the bios version is currently on version 3/07/2023.

Ok, a little update, it seems that the 2.5 ssd that was working fine, now, after 10-15 minutes of turning the pc on simply disappears from the file explorer, but I think its still running as its vibrating, unlike the hdds.
