My G4 Mac crashes during startup
My computer is a Power Mac G4, Dual 1 GHz, 1.5GB, OSX.5 (leopard)
In late December, I started having problems with my computer. When I switched it on, I was getting the message;
"You need to restart your computer. Hold down on the Power button for several seconds or press the Restart button."
When I did what it told me (Hold down on the Power button for several seconds) I eventually got onto my computer normally. The computer would send me an error report, and would give me an option to send it to apple, which I took.
This happend three or four times until in early January when I switched on my computer, and got the message. I did what it told me to do, but this time I was not getting a response. I would see a white background and the apple logo, but no signs of loading. I held down on the Power button, to switch it off, then try again. I would get the same response, sometimes bits of code would interupt the white background, and there was a time when the apple logo changed to a circle with a cross going diagonally down it. But most of the time no signs of loading, if I did not switch my computer off it would show the white background and apple logo for hours (I've tried it). Eventually after turning off and turning on my computer, I get a loading response, (the circle underneath the apple logo) it looks like the computer is going to run normally, but then it switches it self off.
I have tried doing trouble shooting like reseting the computer's parameter random - access memory (PRAM). I start up the computer and immediately hold down the Command, Option (alt button), P and R keys until I hear the startup sound a second time, but all I get is the white background with the apple logo. I have even changed the battery but no change.
When I turn my computer on and immediately press the Media Eject key on my Apple Pro Keyboard, the CD/DVD tray comes out. I was wondering, if I start up using the Mac OSX Leopard CD would that solve the problems and would I lose applications, files and other data that I saved on my hard drive.
