I need some definite help with my computer. I keep getting these kernel panics (screen grays a bit and a message in 4 languages comes up telling me to restart.) I've already had a few today and I had probably five yesterday. This last time I restarted after one my dock preferences must have been reset because it was much bigger, and doesn't hid when the mouse isn't on it, not to mention that it has all the wrong apps. I don't know what's causing this. I wasn't getting them for awhile and the last couple days I've been converting a lot of music to AAC and I started getting them again, more than ever before. I don't know if my computer is somehow overworked by converting music and doing other general tasks, but it's sure hard to get anything done when it crashes every couple minutes it seems. Oh, by the way, I'm using an iMac G4 800mhz. Please help me.
