This afternoon, my G5 iMac freeze up. I was forced to shut down the computer using the power button. Every time I restarted my computer, it would keep freezing. Originally, I thought it was because of Firefox 3 (bugs?) which I had downloaded the other day. However, I deleted the Firefox files, but the problem kept occurring. I was lucky to be on the computer for 3 minutes before it freezes. I checked on a lot of sites and it seems like using my install discs to re-install the start up disk would solve everything. The first time I tried re-installing it while keeping network settings and all files. However, by time I got to the second disk of the install, it began freezing up near the end. I assumed that the problem was one of my files, so I decided to just re-install the startup disk and removing everything to start fresh. Once again, the first disc installs fine, but disc two (garageband, fonts and ect) keeps freezing. Now I can't even get even get past the install screen and since it keeps freezing on disc 2, I'm stuck there. I've been at this for nearly 12 hours and I really have no idea what to do. There are a few small scratches on disc 2, however; the computer still freezes without the disc in it. For whatever reason, it never does when it's installing the items on disc 1. So idk if the problem is disc 2 or not. I've had this computer since Sept 2005, so I no longer have a warranty. Details: 17-inch iMac G5 (Ambient Light Sensor) 1.8 GHz PowerPC G5 processor with a 17-inch screen Any help please? ----------- *EDIT* Since doing this post, I started up the computer in Safe Mode. Through Safe Mode, Disc 2 was finally able to finish installing. I am now able to get back into such things as the Disk Utility. The computer still freezes when I'm not in Safe Mode though. But I'm thinking being able to to finally log back in my computer *Even in Safe Mode* is a big deal and shows that my problem might still be fixable. So now, what do I do? Since I can only be in Safe Mode, I can't be online on the Mac.
