Yeah, Charles is right about the name, but the feeling is the same. Those tiny contacts inside the RAM slot are so easy to miss. You can stare right at a bent one and not see it until you shine a light at just the right angle. A single one out of place breaks the whole connection and the machine just acts dead. It's why a magnifying glass is the real MVP for this kind of detective work.
Oh man, I gotta push back a little here. I've definitely had bent pins inside a RAM slot itself, not just the CPU socket. It's not as common, sure, but I've seen it on older motherboards where someone shoved a stick in backwards or at an angle. The little metal fingers inside the slot get all mangled up, and you're right, a magnifying glass is a lifesaver for spotting it. I actually had a Dell Optiplex once that wouldn't post, and I spent three hours re-seating RAM and swapping sticks before I shined a flashlight in there and saw one of those tiny contacts was folded over flat. So yeah, you can definitely bend those things, not just the CPU ones.
That's a classic, but just to be clear, a bent pin would be in the CPU socket or maybe a USB port. RAM slots have those little contact fingers inside the slot itself. A single one of those being bent or dirty can absolutely cause a no-boot.
