Jealous iMac?

[woowoowoo]

I've just signed up - apologies for joining in my hour of need, but that's the way it is!

I've just bought a new eMac - lovely! but, I had intended passing the perfectly workable iMac DV400 onto my daughter for study.
I used 'Target Firewire Disk' mode to copy all my files across, but almost straight away the iMac started playing up.

First symptom was a 'tearing' of the screen image - looked exactly like using the photoshop 'wind' filter @10 pixels/0 degrees on the green channel only.
Then the image started to wobble - over a period of several hours (while I tried to think what had gone wrong) distortion got worse.
Finally, it started just dropping power - turning itself off after a few minutes (off - not just sleeping!).
Now, it will start up and everything looks fine for about a minute, then the wobblies hit and a minute later it's dead again.

I suspect a power supply, but what are my options for diagnosis/repair? or do I cut my losses, pull out the almost new 80gb barracuda and 1Gb ram and cut my losses?
Do you think my iMac is jealous of the new mac? ;-)

Sounds like one hell of a virus.

I'd jsut call your local authorized Apple dealer and ask them what they cahrge for a diognosis. From there.. you'll know whether it's worth the trouble.

For what it's worth.. I've never heard of a Mac virus that will do what you describe. That dosn't mean it can't happen. But odds of it being a virus are 1 in a million or better. After all.. it is a Mac.

It sounds like you have too much on your circuit! I've seen siliar things in the pst, but not between imac babes in a catfight! Does your "old faithful" act up with nothing else plugged in with it?
