I had this problem once and it did not go away until the next OS update!
I'm not familiar with Macjanitor but it probably allows you to run the CRON jobs that would normally run if you left the machine on overnight.
That said, I didn't catch what version of the OS you are using, or if all your updates have been done. In a previous post you mentioned a Dial Up connection which must be very tedious downloading all the required updates.
By the way, the "screensaver" you refer to is probably the Desktop where all the icons sit. It turns blue right after the Finder shuts itself down. The Screen Saver is the screen you see when the machine has been idle for a while and disappears when the mouse is moved or the keyboard touched.

Hello,
My Ibook G3, 800mhz, 640ram, 30 gb [22.85 free] has developed a fairly consistent shutdown problem. Whenever I'm going to shut it down for the day I first close all programs, then next choose 'shutdown' from the menu; lately, the screensaver will turn to blue, the 'spinning wheel' will begin, and remain that way until I've got to leave for the day. At that point I press the power button until it fully shuts down. I'm careful about maintenance; Macjanitor several times per week, Disk Permission Repair usually once a month. I've checked several forum archives, but no issues appear similar. No other issues with it; if it lasted for another ten years I'd stay with it; a fine machine. Thanks, Eric
