You're welcome, Peter. Glad you had the moxie to pursue some of the other little tricks instead of giving up when it didn't boot properly the first time. Sounds like it had a little trouble finding a viable OS (that's what the blinking question mark means). You might want to check what drive you have set as the startup drive. MacJanitor runs the Chron processes (unix maintenance stuff that runs early in the morning if you leave your machine always on - never runs if you don't). I run it 1 or 2x a month. Apple jack is good for cleaning up OS troubles. A little regular maint will keep the old machine humming along for a while yet. FWIW, I'm still using a Rev B iMac I got new in 1998! Dan
