Jan 6, 2013 10:11 AM in response to Narciss94by Texas Mac Man,★HelpfulYou are having a kernel panic. Have you recently made any hardware changes like adding RAM?
Kernel panics are usually caused by a hardware problem – frequently RAM, a USB device or a Firewire device. What external devices do you have connected? When trying to troubleshoot problems, disconnect all external devices except your monitor, keyboard and mouse. Do you experience the same problems?
To eliminate RAM being the problem, Look at this link: Testing RAM @ http://guides.macrumors.com/Testing_RAM Then download & use Memtest & Ramber.
Do you have an Apple Hardware Test disc (the AHT is on the Install/Restore DVD that came with your Mac)? Running the Apple Hardware Test in Loop Mode is an excellent troubleshooting step for finding intermittent hardware problems. It is especially useful when troubleshooting intermittent kernel panics. If Loop Mode is supported by the version of the Apple Hardware Test you are using, you run the Extended Test in Loop Mode by pressing Control-L before starting the test. Looping On should appear in the right window. Then click the Extended Test button.The test will run continuously until a problem is found. If a problem is found, the test will cease to loop, indicating the problem it found. If the test fails, be sure to write down the exact message associated with the failure.In some cases, RAM problems did not show up until nearly 40 loops, so give it a good run.
May be a solution on one of these links.

Jan 6, 2013 11:09 AM in response to Texas Mac Manby Narciss94,Hi Tom,
Thanks a lot for this really complete answer. I'm currently running Memtest on the PPC.
I'll let you know how it goes as soon as the test is over !
P.S : I didn't find anyway to download Ramber. It seems like the website that was hosting it is down ..

Jan 8, 2013 1:10 PM in response to Narciss94by ScottS1964,★HelpfulRecently had a nearly identical problem with Panther. Was trying to do a complete reinstall and would get the grey screen with logo. After a while it would ask me to reboot by holding down the power button.
Turns out my CD/DVD drive was going bad. While it had been reading almost every disk just fine, it wasn't reading all of the install disk. I wasn't sure if it was the drive so I simply put my Windows PC next to my Mac and turned both systems off. I then unplugged the CD drive's ribbon cable from the motherboard of the PC and plugged it into the motherboard of the Mac (after unplugging the Mac's ribbon cable). I turned on the PC then the MAC and held down the "C" key and did a complete install from the CD drive in the PC.
This was a quick and dirty way that told me I had a bad drive while doing a complete install.

Thanks for your answer ! That's what I was thinking, and I'm glad you confirm that. I must find another CD drive because all I've got here is 4 differents Macs, and none of them has an easy hardware to play with..
I'll find a way, and I keep you posted about what happens to me !
