Hey, long time no PM

I am fine
By the way, i looked through the manual and page 15 & 16 describes a selftest.
did you executed that procedure yet ?
As for the legs of the chips, it usually is working when you just reseat them, the "scraping" from reseating many times cleans the legs and make contact again.
if not, try some alcohol on a qtip but becarefull not to break off the legs!
if its really corroded, you can use very fine sandpaper and sand the legs.
After that you also need to check if the sockets are corroded, and maybe replace them.
whatever you decide to do, it never hurts to check continuity by putting one probe from your multimeter on the leg of the chip and the other on a trace on the board and check continuity.
although that is some work, you are sure that the legs make contact with the corresponding points on the board
