Hi.  Have an iBook that originally had Panther on a 30 GB drive.  I upgraded to a 160 and Tiger, and for a while, it ran just fine.  Then it started to freeze after running for 8-10 minutes, no response from the mouse, no movement on the screen.  I hold the power key down to shut it off; if I start it right back up, it will get past the gray (apple) screen, you hear the disk start to read, then it hangs at the blue screen.  If I wait a half hour or so, it boots up normally, then 8-10 minutes later, it starts the whole thing again.

I have read about the "shim" fixes, and loose chips, it does not appear to be the same thing.  There's no apparent graphics problem, i.e., lines or blanking out.  Applying pressure to the components has no effect.

BTW, I reinstalled the original 30 GB drive, have the same problem.

Does anyone know about the transfer pads on the heat sink?  Do they go bad?  This does look like an overheating situation, and the graphics chip is a strong candidate.  It doesn't feel excessively hot on the outside, though.

Any ideas OTHER THAN the logic board? I'd like to try everything else first.

Thanks for any advice.
