I remove the memory card, and stills hapening..
I want to know is this is just a kernel problem that it stops formating or is a hardware problem involving the LogicBoard or Graphic Card..
Thanks

I guess memory can fail over time. I just haven't experienced it myself. (Or heard of it, but it is a piece of hardware).
You can test your RAM by either using your system installation / restore discs (the original grey discs that came with your machine) and pop in Disc 1 and reboot the computer holding down the OPTION key and from there, you will get the choice for Apple Hardware Test, which you can use to do a basic test of your RAM.
Second, if you ever signed up for AppleCare and got the TechTool Deluxe disc that comes with it, you can use that too for a more extensive RAM test. Just be careful not to use it to diagnose anything with your hard drive. Just use it for RAM. (Be warned, as their is an incompatibility with Tiger that can ruin your drive. Though I see you have Leopard, so don't even know if it works).
The other test you can do, as suggested by many of the top users in these forums is "Rember" which tests your RAM and should let you know what's going on. I used it once after using it as a suggestion (taking someone else's suggestion and using it for my own testing) and it showed the second module of memory that I bought on eBay--the one that doesn't cause kernel panics--to pass.
You can find that here: [http://www.kelleycomputing.net:16080/rember>
Also, when you get your RAM replacement, I highly recommend getting Apple OEM suppliers such as modules from Samsung, Hynix, or Micron (manufactured by Crucial). They should be trouble free.
I say should because the Samsung 1GB module I bought for my 12-inch PowerBook from OtherWorld Computing has worked flawlessly for almost two years now. The one I was talking about previously, that crashed my 15-inch machine? A Samsung one as well. So, it is true that these Aluminum PowerBook G4s are picky about the RAM installed.

I forgot to ask you... what brand RAM do you have installed? (If you know and it is labeled).
