I just noticed today for the first time that when I boot up, it goes to black, then to one shade of gray, and then another, and then starts up with the Apple. Runs fine from there. Sometimes before the Apple appears, I'll get the folder with a question mark, but then the Apple appears. I just partitioned my HDD last week and I don't think I had rebooted it since then, so it's possible that it just takes a bit longer because of the partitions. I also reset my PRAM and PMU this morning, but it started up fine then. Any idea if there is a problem with my iBook and if I should be concerned about it? iBook G4, 14", 1.42 GHz, 1.5 GB of RAM.
