Hi everyone, I just bought a used Macbook from eBay. I bought it because the specs sounded very attractive for the price it was offered(2.16 GHz Intel Core 2 Duo 1.5 GB 667 MHz). In the description, I basically ignored the seller explaining that the pinwheel at times popped up for seemingly no reason. I figured it would be a simple way to fix it, as the seller explained that "he wasn't a Mac guy" so he wasn't sure how to fix it... So I got the computer and begin to notice that the spinning pinwheel would pop up for absolutely no reason. I'd have one application running and still get a pinwheel for about 30 sec to a minute for no reason. I've used the Disk Utility to check the hard drive and supposedly everything is okay. I've repaired permissions, I've used rember, etc. It just keeps freezing. Do I need a new hard drive? I'm just really confused and frustrated, because I need this computer to record music, and the problem seems to be getting worse and worse. Please help me out. I'd appreciate it.
