They are having problems with a (i think) 2007 imac with 2.16 ghz for 2 duo and 1gb of ram. Recently they are having loading problems were it could take up to 10 minutes just to open up safari or any program for that matter. Its been going on for about a week or so. They are also using snow leopard. I am thinking the best place to start would be to upgrade the ram? Any help would be great! Also what time type of ram would they need?
