 invalid memory access! Well, I shut my computer down last night for once in a week or two. When i turn it on this morning i get the open firmware screen which ive never seen. It read : invalid memory access at %SRR0:01c0ca0a %SRR1: 00003030 then it just gives me the option to "mac-boot" or "shut-down" and when i try to boot the screen goes to what looks like a gray pin stripped suit. I then was able to boot from the apple hardware disk and it "said" everything was good. I also opened her up and cleaned out the dust and reset the pram. Ive never seen a problem like this before so im just assuming its hardware please let me know if im wrong and need to repost in the correct forum. Like i said im lost so any help would be great. Almost forgot : powermac g4 dual 1ghz (mirrored drive doors) 1.75ghz ram osx 10.2.8  |

| Have you tried reseating the RAM? Hopefully that should do the trick. Also, how old is the RAM....is it the RAM that shipped with that computer? If so, it might be time to replace the memory. Try the first solution first though before anything.

| I forgot to say i did that when i cleaned out the dust bunnies. And yes it is some of the original ram along with three 512s. So i guess since hardware test didnt find the problem i have to restart the comp with each stick of ram?? |

| Yeah, you might have to pull the RAM and test it individually if possible.

| Did you open the Mac back up and make sure all the cables are plugged in good? Cleaning the dust out may have loosened a cable somewhere.
