So, my mac has decided that I’m suddenly asking too much of it to run itunes, mail, ichat, safari, and firefox at the same time. I used to have like a thousand things open at once, and it was fine. But now itunes drops out every 10 seconds or so, opening a web page gets me a damn little swirling colors disk cursor half the time, and it’s REALLY PISSING ME OFF! oh, and most of the time, when it does this, the processor is nowhere near 100%. the past few hours, it’s mostly been down under 25% !! Anybody have any ideas what’s wrong? I think the odd grinding noises it makes when i move it are perhaps related to the fan, because i didn’t originally notice any problems (other than when i panicked when it first happened and turned the thing off, and it wouldn’t reboot for a few days) associated with the grinding. it is becoming more frequent, though. as are the freezing spats. i first noticed it freezing though when i was running “bittorrent”, but i’m not running it anymore. any thoughts would be much appreciated.
