I have a powermac g4 (mirrored doors)dual 1 gig with 1.25GB of RAM. I have had it since march of 2003. I am running Jaguar 10.2.8 I am having some weird symptoms and I was wondering if someone could help me troubleshoot the problem. Here are some of the strange things my computer is doing: It often randomly tells me I need to restart my computer by pressing and holding down the start button. ONe time it suddenly shut off right in front of me. WHen I started it back up, the time was incorrect and the date said 1970. Firefox and Safari crash over and over. Sometimes it can't find firefox in order to open it. One time, it kept asking me for keychain passwords and when I entered the only password I would have for my mac, it said it wasn't valid. It often freezes up and I get the rainbow spinning wheel. Sometimes it freezes and I just can't do anything. Sometimes it initially freezes then it goes back to the login screen. Sometimes mail crashes right after I open it. I am unable to print and unable to download anything onto my boot hard drive. the printer does show up on the apple profiler though, so I know it is being recognized. When safari and firefox crash, the console says kern_protection_failure and a bunch of other things, but I am unable to get onto the internet from my house for long enough to post, so I am posting from work where I dont have access to the log. I have tried repairing permissions (over and over....it still repairs something every time even if I do it 4 times in a row.) I have run the hardware test on a loop and everything seems fine there. I also created a new user to see if the problems persisted and they do. I downloaded cocktail (onto another drive)to try to clean up the cache but it won;t mount and gave me an error message (can't remember what it said, but it was a weird one....somthing like a bad tunnel or tube or something). I have plenty of hard drive space available so I know it isnt that. Can someone help? I have a huge project coming up an if my computer doesn't work then I'm screwed! Thanks!
