to the MAC GURUS!
 

I need help..I was playing with OSX themes and the GUI, changing dock visibilty and crap and it wouldnt detect my internet connection..(i have cable) so I made a new user and tried loggin in that way, and now it wont even boot up.. it stays at the blue screen before the icons and desktop icons would come up..help! How can i restart it???

I have a powerbook g4 800mhz on OSX

pop in the utility cd that cam with the mac .... hold down c key to force boot on cd and run the diag / repair program on the disk. to force the power down and up just hold the power button down for 10 seconds.

is there any other way besides using the boot disk? I have it back home..LET ME KNOW
