This goes to prove that computers have a sense of humour, and a very unfunny one at that.

I bought a 1ghz g4 MDD about 6 months ago, from day one i had a problem with the mac freezing up randomly sometimes twice a day, sometimes twice a week, its VERY random, everything on the screen freezes (including the cursor) and if music is playing you just get a beat of music repeating over and over. The only way to regain control is to hold down the power key and restart.

Ive tried reinstalling, rezeroing, removing hard drives, swapping hard drives, removing ram, swapping ram, hardware tests, zapping pram, etc etc etc, you name it ive done it.

I rang apple and they sent someone to collect the machine, a week later it came back, they had found no problem (theres the very unfunny joke). The mac was ok for a few days, then it froze up again.

Ive only recently found out that watching a dvd on the mac is when the problem is at its worst. I had 3 freezes during a 2 hour movie. I tried copying a dvd to the hard drive to see if the dvd drive was the problem, it still froze up.

I was assuming this is a logic board or processor problem, but why would playing a dvd make this so much worse when nothing else i do seems to make it worse or better?

Sorry for the long post, i just wanted to explain the situation in full. Thanks for your help.

That really stinks! Sure sounds like it's the logic board, maybe playing a DVD stresses the IDE controller? I'd try pushing the issue with Apple for sure.
I've got the same machine, only glitch was Panther not liking some third party memory.
Hope you can get it resolved.

A friend of mine has a dual 1.25 G4 mac with very similar issues. Crashes an awful lot. I was certain it was the ram, but we pulled it all out bar 1 stick.. juggled the remaining ram chips about, same thing.. Literally tried everything there is to try, and it still crashes several times a day. This is from numerous versions of 10.2 and 10.3
Machine is a lemon and he's about ready to give up and sell it.

Not much help to you I know, but this isn't the only case of a rogue G4 MDD tower i've heard about. Must be a few around I think..
The worst thing about having a failing memory is..... no, it's gone.
