Hello, I build a pc (ryzen 5 2600, MSI B450 gaming pro, Corsair lpx C16 3000 mhz) but when i press the power button, nothing happens. I removed the cable for the mobo power, and after that I got a red rgb light from my case burning for half a second. And if I press the bios reset button, i see the normal light that oyu got when you reset your bios. Can someone help me please? i removed all the parts and assembled them again, but i got the same problem. Thanks in advance!
