would you prefer to do it, im just thinking of your time is all.
I use an IC removal tool to remove the chips, and try not to touch the legs.

In all honesty, the IC sockets seem OK, they've all tested fine for continuity with a DMM and so have the chips when installed in them.
I would say that some of the IC's are bad anyway - previous owner has probably had these in and out a hundred times before anyway - probably why it doesnt boot.
