Sounds like you have the dreaded graphics chip problem :(.

Firmly press on the bottom near the battery release and then turn it on. See if that gets it to turn on. If that gets it to work, it's only a matter of time before it fails completely. I'd suggest backing up ASAP if you get it working again. There really are no permanent fixes but only temporary such as the shim method or having a chip resoldered. There's a very small chip on the bottom that develops micro cracks in the solder joint thus causing video problems. Applying pressure to that area usually creates the contact needed for it to run again.

Good luck.

You can find a used iBook G4 on ebay for less than $200 these days.

Very easy to buy one, do a fresh install of OSX, then use the Apple Migration Tool to copy over all her settings, applications, documents, etc. It's a very easy process in case you've never used the migration tool before.

If your handy with a screw driver, you can buy the 1 GB ram upgrade (max) for ~$35 and a nice new 80 GB hard drive for ~$50.
