Well,

Today I reflowed the solder and changed the socket I just installed.
It immediately didn't work. Frustrated, I just let the game run for
about a 3 minutes. I noticed that the message of "Bad Ram 1" stopped
flashing, remained constant, and then suddenly BOOM, the game started
right up.

It's held steady since.

Weird....

The only problem I have now is that the marquee lights aren't working.
The bulbs aren't bad but I didn't have my equipment to make sure there
is juice flowing to it.

Thanks for the suggestions, though.
