My mac is being very windows like, and I'm getting quite frustrated. After 8 months of a perfectly cleanly running system (except once when I tried to run themes through themechanger on 10.3 but I was using the 10.2.8 version, as 10.3 was brand new), my computer has crashed on me 3 times in the last week. And it NEVER crashed before this. I have no idea what is causing it-I haven't done anything big with software in a long time, I've been doing the exact same stuff and treating my computer the same as I did for 8 months before hand, and I can see no indicitive patterns whatsoever. Can anybody tell me what to watch for that might be causing this, so I might be able to fix it? Thank you so much. Other possibly relevant information: Viruses have been flying around campus like mad. But....I haven't heard of any non-windows viruses. The first time, I had probably 15 applications open at one, and was weighing quite heavily on my system. the other times, I had several things open at once, but not that much, and I usually never worry about that. A friend said it might be corrupted files if I hadn't restarted in a while, and I almost NEVER restart...but I have been lately, and did so right before the first crash. here's how it happened, each time. I was going along, minding my buisness, and the music I was playing in itunes would stop. I could move the mouse, but not click on anything, and force quitting, etc. didn't work. After a while, another second or two of music would play, and then stop again, so I thought it was maybe just really backed up. But, eventually the mouse wouldn't move, and then I'd reboot. itunes was always open, and I was always playing music, but that is pretty much the case if I'm anywhere near my computer anyway. And, I think I might've been in Safari each time it crashed, but I only noticed that the last time, and again, I spend a lot of time procrastinating online. Any help? I'm starting to stop bragging about my computer's kickassness to windows users, and it's painful....please help me get mine back to it's usual rock solid, left on for months and constantly abused state. I also think I might have the AIM worm that's been going around campus, as iChat is being extremely weird and buggy, and that's not helping my cause.
