Ben: You hit it on the head! I opened up my PB 190 and pressed down harder on the RAM expander module I installed back in 1996 and it cleared up the problem like magic. I don't know how techie you are, but can you explain exactly why a loose memory connection creates lines on the screen instead of outright corrupting the screen entirely? Thanks! What's disturbing is that the foam strip that Apple warranty-installed under the keyboard to prevent that very problem obviously flunked the job. I'm also troubled that TechTools 3.08 didn't catch any hint of such a problem even under all out hardware diagnostics. Again thanks a million!
