People sometimes recommend using something like a credit card because it's relatively soft and flexible, and if you line it up carefully you can use the other pins in the row and column as a guide. But more concerning is those possibly empty pin holes. In the before picture you can definitely make out that they used to hold pins. I think I can see one still attached. No idea on the other.
yes using something that can run along through the gap between the pins like that is how i have fixed bent pins on amd cpus
though its easier with those than with intel because the pins are on the cpu not in the socket
i used to use a stanley knife blade to run along the rows in both directions
the flat side of the blade that is not the sharp side
not sure if a credit card wouldnt be too big or too thick and probably too awkward to use in the intel socket
and your eyesight is more than likely better than mine so you might be right that the pins were there before
not sure on that myself to be honest
