Hi all, I have a 24" 2.4GHz Aluminum iMac. Lately it's been getting on my nerves. First off, I put it to sleep every night at the same time I go to bed. Yet, at exactly 3:20AM it wakes itself up. If I remember correctly, I somehow told it to do that [but was supposed to be PM] for when I got home from school, and that it is somehow set to AM and I forgot how to stop this. Secondly, the speakers distort the sound every once in awhile. I'll be listening to music for a good amount of time, and the sound will increase a bit and sound almost like it's coming through a metal can, if that makes sense. It sounds like a high ringing that blends in with the music. Another problem is that the apps crash or hang a lot, even now I was simply playing a song on iTunes and it crashed. In fact I won't be able to use iTunes until I restart. A lot of the times I'll be using iChat, and it will forget I have a webcam, sometimes it'll just crash out of nowhere. A lot of apps do this. Finally, the system itself seems to be a bit slower, I'm seeing a lot more of the "beach ball", aka the colored wheel. I don't have much on this computer, just a few extra apps, and the biggest portion of files are music and photos. But that's about it. What should I do about this? An Apple Store is too far away, and I use this too much to be able to ship it off really, so what do you guys suggest? Help is greatly appreciated and thank you in advance.
