Sorry,Sorry, I was away a minute.
From the Apple menu, select 'About This Mac' and tell me what the processor speed is. This will let me know what types of diagnostics I can have you do that may help.

Why, have you tried this? This will reset the main power controler among other things.
trying it now. it sounded bizarre is all, but I am a mere civilian, inexperienced in these things.
It's up and running. Not sure how to trigger the behavior - it usually starts after it's been running a while
This is the Apple support article that this is from. Intel-based Macs: Resetting the System Management Controller (SMC)
it does seem to be perkier
so far so good

You may want to take it to see an Apple Genius at an Apple store, they will confirm my diagnoses or they may be able to fix it fairly cheap.The Maintenance Widget and Repairing Permissions, they stuck together.
They will download automatically.
ok. Well, the black line on the display is back. usually means it's about to lock up :(
I'll try the widgets you suggested
any other suggestions? do you know about how much logic boards run if that's the trouble?
My experience with Apple is very good for this type of repair. I just had one iBook and one MacBook Pro logic boards replaced and each was $310.00 for any repair needed on the machines, from keyboards to screens.That is why I suggest Apple, I don't know where you are so I don't konw the nearest store.
I do know that $310 is way cheaper than a new Mac.
