I just bought a new Ryzen 5 2600X and I installed it into an MSI B350 Tomahawk, and now every time I start the PC, all of the lights in the PC will flicker. The CPU is good, I tested it, but the screen won't turn on and the lights are all flickering. I think it might be a power issue, but everything was plugged in until it clicked, and I have no idea what it could be. It doesn't just turn off, it'll stay on until I turn off only when I switch off the PSU. I have enough power for the whole PC with an 850W PSU. Any help would be greatly appreciated!
