warm up issues can also be related to power supply. Capacitors deteriorate over time. If voltages are a little low until the components are warmed up, it may be that the supply is insufficient to guarantee proper operation when cold. Checks with a multimeter can help.

I'd remove, clean and re-insert the PLCC socket chips ("INGOT"). However, since your problem changed with DRAM chip location, that alone probably won't fix it.

Do you use a surge protector, or is the power straight from the mains? :)
