We have a 9-year-old iMac, and it's still running fine except that it started to slow down. So we decided to upgrade the RAM to 3 GB. Following the instructions on Apple's support site for replacing RAM, we opened the ejector clips, removed the old RAM, put in the new RAM, pushed it in with thumbs, not the clips, till it clicked in to place (though possible I pushed one slightly too hard/far? It looks about the same as the other one in terms of how deep it is though, and they are too hard to remove without the clips which are already open), and tried to close the ejector clips after them to lock it in place. However, the ejector clips don't want to go in. I know they had a little resistance when originally opening them, but I'm concerned that if I try too hard to close it again that they will break or damage something. Is this a possibility?
Further, we simply put the iMac back upright and plugged it in, and it actually is working and reading all 3 GB of RAM (and running more smoothly than before). Does that indicate that we did something wrong or right?
Should we leave well enough alone, try to force the clips shut, or what?
