Rig: Asrock B450M Pro gaming 4 Ryzen 3 2200g HyperX 8gb 3200mhz X2 Sapphire RX 570 Samsung 860 evo nand 250gb ssd sata/WD blue nand 500gb ssd M.2 So I had my new rig up and running for a couple of weeks, decided to upgrade my hdd (secondary drive) to ssd so got a WD blue 500gb m2 slot. When I first installed the ssd, system wouldn't recognise it, i realised it was because i put it in the ultra m2 slot which wasn't the right 1. So put it in the right slot and that's when it all started. It wont post and doing a boot loop after 30 secs. So went through the list of usual tests, boot with no drive, 1 stick of ram, cleared cmos and removed battery and still nothing. As I wasnt able to test each component, I have gone round pretty much replacing each of them. So far I have replaced the ram, mobo and even now upgraded cpu to a ryzen 5 1600x. It's still doing the same thing. I don't think its gpu as I put my old gpu into the rig and it does the same loop. Could it be the psu? Can anyone advise anything?
