I disassembled this iBook and checked all connectors in the process. I took it all the way to removing the hard drive. Not sure which connector was loose, but upon reassembling the iBook, the problem has gone away (knock on wood!). Don't know yet if I have permanently solved the problem, but have been using it for several days with only one situation involving the freezing problem.

Recommend you give it a try.
