How can I clean a RAM slot?
Got a donated G5 20" iMac with several problems. After replacing power supply, it began to work. Then tried to add RAM (matching chips), but top (2nd) slot doesn't work. With RAM in 2nd slot, iMac experiences constant kernel panics.
Original suggestion from multiple sources said it was likely logic board problem, but this Mac is too old to put money into that. Since it's 6 years old, and the 2nd RAM slot was never used, IS IT POSSIBLE that the RAM slot merely needs cleaning? (One tech guy suggested cleaning connectors on the RAM itself with an eraser, but since it was new and clean, I wondered about the slot itself.)
Can the RAM slot be cleaned safely? If so, what should I use? (Alcohol or other cleaner? How to apply if any cleaner can be used? Or is there something like a pencil eraser that could go into the inside of the slot?)
Is this a good question?
