I am running a dual G4 1ghz i have been using this computer fine for the last few days, today i went to do a tiger update and it kepting giving me an error while it was trying to download it saying that the file was curupt it happened twice so i decided to restart. it got to the grey apple screen and the wheel just spins and the coputer never boots up, i put the apple hardware test cd in the computer and ran the test and it gives me a memory error

i assumed that it had something to deal with the memory chip that was in the j20 slot, so i removed the chip and booted ut up and still had the same problem, i replaced the ship and the computer starts up and goes to the grey screen and shuts down....any ideas?

the issue is solved, after talking with kingston about the memory it ended up being a bad hard drive. The apple tech support was a waste of time, i was told that since my apple hard ware test cd ran correctly and said that the memory was the problem that the hard drive was fine. After removing and switching around all my memory i figured i would try a hard drive from a different machine. What do you know that fixed it.
