Okay so here it is - my computer for the last two days has been acting a little strange. Yesterday after it started up and went into screen saver mode i got the screen that says something along the lines of "Your system need to be restarted. Hold down the power button...." so i did that and every thing seemed to be okay. Today the the airport card was not picking up a network so i restarted the airport base station and then it registered the network and everything going okay until i got the same screen as yester day "Your system need to be restarted. Hold down the power button...." but when i restarted the computer this time i got a different message: can't prune Apple powerbook3,5 4.53f2 boot rom etc. now i just tried to restart it again and it loaded up just fine - but i want to know if this will keep happening?!
