Needs reboot after some running time
I have a old PowerBook that after some running time grays out the screen and displays a message saying that the computer must reboot and I must press and hold down the power button.
Any ideas what the problem is? I have reinstalled Tiger on it, deleting the disk, but still I have the same problem. Can it be that it overheats after some time? I have just taken it apart and checked the fans, they look good, but I do not know if they work or not. Can it be the cooling paste that is to old, or?
