Hardware 12" iBook G4 1ghz 768mb ram, 40gig HD, airport extreme. Almost daily now I'm having my system freeze up completely. The mouse still moves but everything is frozen and it does not unfreeze so I have to do a hard reset as I don't know any other way to unfreeze it. A lot of times this seems to happen when I try to drag MP3s from a folder into iTunes. I drag them onto a playlist and bam.. everything freezes.. reboot time. After reboot, I do it again and the MP3s load in and play just fine. It doesn't only happen when I do this but most of the time it locks like that it's when I drag files into iTunes. Other times it's just random but seems to be when I have a lot of stuff going on. I do a lot of graphic work and web development / java programming so I'll often have a lot of stuff going at once but my gosh Windows didn't lock this often on me! 3 times I have gotten the black screen of death. This is a weird thing that happens.. out of nowhere my screen dims and a black box comes up and says "You'll need to restart your computer now" and it says it in like 10 languages. This is also NOT my first iBook and although iTunes never did this on my G3 iBook, I did have lockups and the black screen of death a number of times though which is why I sold it and got the G4 ibook. I'm really upset now because I love the mac so much but my god why all these lockups? Is there something I can do here? Another app that seems to be tied to lockups is LimeWire. I only run LimeWire once in a while for that '90s music nostalgia fix yet it seems that it's way more prone to lockup when LimeWire is running. I guessed that this might be a hard drive issue but I ran some disk checking software and it told me nothing was wrong. Help! I so wanna get a G5 iMac but I just don't know that I can justify it if it'll do the same stuff the iBook is doing. That and I really like having a portable computer even if right now I use it mostly on my desk. Also Java apps have run better since the last java update but still jEdit and Eclipse run kinda sluggish compared to Windows and Linux and Tomcat crashes daily on me.... A co-worker told me that at his friend's mac never has these kinds of problems. Just don't know what to do. Thanks for any help.
