Have my iMac for a month and last week problems started. I called tech support yesterday but they said I need to call when the problems are actually happening. Maybe someone out here could help me figure this out: a week ago it started when I turned on the computer and went to Safari--would not connect to internet. I would then quit the app and then the computer would start a beeping noise. When I hit the space bar the beeping would go off. I would then go to Firefox--the internet would work and then I could reopen Safari and it would work. This happened for a few days. Then this weekend when I would open any program and go to any of the top menu choices and move the mouse there to go to a drop down menu---the drop down would close before I could move my cursor over to chose something. Then I went to iPhoto to open an album and it would not open to see the pictues within an album. I didn't have time to call the problem in over the weekend--yesterday I called but the computer worked fine all day so they couldn't trouble shoot it. Obviously I still have a problem--anyone think of what it could be?
