First, a word of advice: never use an ultrasonic humidifier in the same room 
as a computer with a fan...

OK, here's the situation: Within the past two months my Mac will occasionally
start "fuzzing" the pixels on the screen.  I mean that everything starts jumping
a couple of pixels back and forth for about a second, then clears up.  This
only seems to happen when it has been on for a while.  I live in a rather
dusty environment, and thinking that it could be overheating caused by dust
coating the inside, I opened up my Plus and used compressed air to blow all the
dust and *calcium deposits* off the boards, tube, etc.

It didn't really help.

What is the next step?  Is this indicative of something major about to go wrong,
or does it just need a better cleaning?  BTW, my setup is a Mac Plus with a 
Kensington System Saver, and a Jamine DD70 which my Mac sits on top of (I've 
elevated the Mac off the drive an inch to see if the heat from the drive was 
causing problems, but no luck.).  Thanks in adavance...
