Re: FREQUENT Kernel panics Motion 3 in 10.4 PPC G5

Hi, I found this thread when searching for a very similar problem.
Sudden and hourly crashes ranging from the "you need to restart this computer" message, to sudden freezing or disappearing of one of my 2 screens.
I usually send Apple the crash report each time I restart if it stays alive long enough.

After trying reinstalling OSX10.4 from the system disc and the problem still remains, I've been examining my crash logs, here's the latest:

-----------------------

panic(cpu 1 caller 0x54E33AEC): DART entry exception: PCI0 write logical page 0x00000

------------------------
Thanks for the suggestion of pulling RAM modules out - I'll try that next, if this doesn't work:
Due to just one of my screens going blank in some crashes, perhaps the problem is my video card.
I gave the board a jiggle and unplugged the screen plugged into the special Apple monitor out port (AD?).
I've had time to type this, so it's looking good so far.

Any suggestions gratefully received.
