My 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 clear 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?
