Just acquired a 500mhz G4 Tower. (I think that might be a Sawtooth). It came with 9.1. But I want to put Panther on. It kept freezing on the Panther install so I took out all but the 128 stick, partitioned the 20 gig drive so the first partition was about 7.5 gigs and then was able to install but not get through registration. So I bought a 512 chip from OWC figuring it might be memory. Installed the memory and got through registration. But now it freezes upon opening hard drive partitions - usually while the window is zooming up or the mouse freezes or the monitor goes to sleep and I can't get it to wake up. Reset the Pram (3 chimes). Very frustrated. I would appreciate any thoughts or troubleshooting ideas. Thanks so much, Linda -------------- next part -------------- An HTML attachment was scrubbed...
