So basically, I bought a NEW CPU Ryzen 7 5700x. First time i put it on my older motherboard ASROCK A 320M-K and when i turned on the PC, theGPU wasn't giving me a picture. The blue control light on the GPU was turned on but the GPU didn't give me a picture. So basically i put my older CPU and it worked fine.

Then later i bought a new motherboard MSI B550 A-PRO. And i still have the same problem. But on this Motherboard i have DEBUG lights and the only light was turned on was for CPU

Could it be possible that i need to update the BIOS with an older CPU? Or the new CPU is just broken?

GPU is AMD Radeon RX 580
