Not sure if the G-4 group is still up and running, so I'll try to get some help here. My son has a G4, running, OS X 10.4.8 He called and has two problems and was hoping someone might give me a little insight to throw his way. 1. Everytime he starts up he gets a message that says "Start-up disk is full". I seriously doubt if he has that much on his hard drive. I had him click the hard drive and open-apple-I and it says 0 hard drive space left. 2. His 20" digital monitor is sometimes blank at the top. Its the older style digital monitor. Any suggestions would be appreciated. Thanks Jerry
