I have a Mac Mini 1.25 ghz with 512 mb of ram installed. Every day when I use the computer, the beach ball continues spinning and the programs do not respond. Sometimes I also have to restart my dsl Modem which is from Verizon. I always have to restart the computer and then it goes back to normal for about twenty minutes and then it happens again. I am only running safari, mail, msn messenger, and ichat. What is the problem? Is it the Ram or what?
