Hello all, <br><br>I have had an ongoing problem with my G4 Sawtooth 450 AGP freezing randomly. Sometimes it will run for days just fine, then all of sudden one day I cannot even open a window in the Finder without it freezing. I had the machine hardware checked at the local Apple retailer and they could find nothing wrong. So I replaced the hard drive, installed new copy of the OS 10.3.9, reset the RAM to a different slot and did several runs of MacJanitor and Apple Disk Utility to repair the permissions. I now want to try Applejack to see if that may fix my problems but the machine will not boot into Single User Mode or Open Firmware. Any suggestions would be greatly appreciated!<br>
