Hi, I have an iMac that I bought around October of 2009 that's running Mac OS X Snow Leopard (version 10.6). I haven't used it for the past year or so because it's gotten so slow to respond-whenever I open up a folder, surf the internet, or play music, etc, it takes forever and a day to perform the function I want it to. The mouse cursor will just spin and spin and spin! When I play music, the music will constantly stop and then come back on again, like something is working in the background that's slowing it down. Recently when I went to use it, however, I turned it on and the login screen came up, but then it just sat there on that screen with the mouse cursor spinning. I've powered it off (using the button since I can't use the mouse) then back on, and the same thing happens. This is something new and I don't know how to get past the log in screen. I admit I've always been a PC user so I'm very unfamiliar with Macs, and this experience has not made me very fond of the Apple world. Can anyone advise me on what they think may be going on and how to proceed from here? It has 500GB and still lots of empty space, so I can't figure out why it's acting this way, because it acts like it's bogged down or something. Unless it's a memory problem? I don't have all the specs on hand-I'd have to look it all up. Thanks for any help!
