on my original 6100/66 I have an odd issue with the computer. I need to put a lot of force on the two cards on the left side of the computer to get it to boot. If I just turn it on with the power button, i get the chime, but nothing comes up and the HDD spins up but doesn't seem to load anything. Thus I have to put a lot of force on the cards and then turn it on and it gives me a happy Mac and restarts and the boots up. Any ideas on why this happens?
