Hey everyone, I'm having some really irritating problems with my MacBook (running Tiger) as of late. I've been trying to use MacScan and ClamXav to see if they'd solve the problems, but so far, no dice. What's been happening (as of yesterday and today) is that my Mac Messenger will open, start to login, and RIGHT before it actually signs me in, the program shuts down. Today, my iTunes started to do the same thing. For the past maybe week and a half to two weeks, it's been doing something weird - Safari would freeze, then everything would freeze, forcing me to manually shut down and restart my laptop. Once I did, everything worked normally and fine for awhile until the same thing would happen again. No programs were acting weird, it would just freeze and I'd have to shut down. Now, however, MSN and iTunes won't run properly and it's driving me mental. I tried repairing permissions - but to no avail. It gets to a certain point and then the Disk Utility freezes and I have to shut down and restart. This is driving me absolutely MENTAL. I'm about ready to throw a $2000 laptop against the wall and then beat it to smithereens with a baseball bat, haha. Any help would be very much appreciated! I really don't wanna lose all my files (I'm a college kid, so needless to say, I don't wanna go through the hassle of losing all my notes and such), so any advice short of having to resort to that is what I'm hoping for. But if it's absolutely necessary, I guess I'll have no choice. Thanks guys, I really hope one of you pros can help me out!
