I have a 2007 Mac Pro (OS X Tiger 10.4.11) that cannot boot up anymore since a few days. I see the grey screen with the apple logo and the rotating circle. After a minute or so I get a kernel panic. All peripherals except the Apple keyboard are disconnected.
I tried booting from my install DVD, this gave a kernel panic too.
When booting multiple times in safe mode, this is the last line on the screen: "localhost mDNSResponder: Adding browse domain local"
What I already tried:
-Downloaded and burned another Install DVD, same problem (first disc is original)
-Switched the memory modules and booted with just 1 inserted
-Ran the Apple Hardware Test, no problems found.
-Replaced the DVD drive
-Ran fsck -fy , no errors
-Cleared the PRAM
Any ideas?

It is probably your video card. The 2007 MBP's were prone to this.
Here is how you can tell. Download the Ultimate Boot CD. Burn it to a DVD or a USB Stick
You will launch Linux with a ton of useful diagnostic tools. Run everything, but especially the video display diagnostic tool.
Mine was throwing errors and I was able to definitively find the cause of the problem. I was able to find a guy in Tampa that would upgrade the video card on the Logic Board for about $100. I did the service and it worked great. MBP still running to this day. Let me know if you are interested and I will post his info.
