I just updated my old PC with fresh Mobo, processor, and RAM, but it didn’t work. The machine starts up but then fails completely. No video or any sound at all. I used a Ryzen 7 5800X on an Asus Gametuf B550 with Corsair Vengeance 32GB DDR4 and an RTX 2080. I also tried the GPU and the graphics connector, but nothing happened. Please help!

I didn't catch it. The salesman at Micro Center said it was fine, but I won't know until I get home. What determines that specific version? Please excuse my confusion. Is it the processor or the motherboard? Where does this advice come from?
When 5xx boards were initially introduced, they were meant for the 3xxx series Ryzen. The 5xxx line followed later and needed a BIOS update for the new generation of 5xxx processors to function properly. Over time, it seems there are very few, if any, 5xx boards remaining in stock that have had the necessary BIOS applied by the manufacturer—though it's possible some older models exist, they're unlikely. The best way to confirm is to look at the motherboard's specifications; a box indicating "5th gen ready" would be reassuring.
Video ports on the motherboard won't operate without an APU CPU. Since your CPU lacks integrated graphics, these ports remain inactive.
There are no audible beeps or warning signals indicating issues. If everything checks out, consider seeking a second opinion from a friend or visiting a Micro Center for assistance.
Need to examine all these matters upon returning. More updates soon. Lol
It depends on the situation, but an updated bio might affect whether a video is needed.
