Here in TikiMexico I like to pick up the odd computer repair job. It helps pay the rent and it lets me see into other people’s equipment. Often there’s years of caked dust and cat hair. Occasionally there’s some fun stuff like plastic toy soldiers or notes from other technicians. Other times, there’s just a horrible hardware failure.
As far as I can gather this RAM stick must not have been seated properly, or some electrical fairy was not appeased. One of the more impressive failures, the adjacent pins have actually fallen after melting their plastic casing.
