Question B450M Pro 4 Gaming

[Silverscreen07]

My new rig:

Ryzen 3 2200g
Hyperx 3200mhz 2x 8gb DDR4
Sapphire nitro RX570 4gb
Evga 600B

So everything was working fine for a week or 2, I decided to get the wd blue 500gb M2 to try get rid of my old HDD, firstly it didn't recognise the SSD and then I realised I put it in the ultra M2 slot instead of the correct 1, so switched it. But ever since it was put in, the PC has decided not to POST and does a loop. I have tried to reset everything and test with 1 ram stick etc. I have cleared BIOS and taken battery out and back in and nothing seems to be working? I don't understand as it was all working.
Anyone got any ideas before I send the mobo back for a replacement?

Are you on the latest BIOS update for your motherboard? Are you sure there are no SATA devices connected to the SATA ports while your M.2 drive is populating the board? Speaking of M.2, mind sharing a link to the SSD?

...Does it work without the drive installed?

Yes, I did check the bios version when I first had it up and running.
I had 1 ssd and 1 hdd connected to sata but they weren't on sata3 which is the 1 sharing the line with the m2 port. Should I have had them disconnected?

No, tried it already without any drives connected

So I have replaced the mobo, ram and even upgraded cpu to ryzen 5 1600x and it's still looping. I've tried with 1 stick of ram, cleared cmos and removed battery, can anyone help? Could it be the psu?

It's not the psu, tested and it's fine. Am going to attempt to get a different ram
