It's possible you killed the RAM. Why would you touch the RAM? There's a reason PC cases don't have easy access holes. Don't touch components when the PC is on.
that's because motherboards have certain slots where the RAM should go in. EG. My motherboard has 4 RAM slots and I have 2 sticks. I plug them into slot 1 and 3.
