Hello everyone, New member here, and first time posting
Hoping to get explanation/advice regarding my iMac G4 1.25GHz 20"
The iMac works great, I use it solely as an iTunes machine with various iPods and as a jukebox (it's my only machine that holds my entire music collection). However, recently, the iMac has literally been shocking me. Areas that shock while the iMac is running/plugged in are primarily the metal neck, and also the ground/external shields of Firewire and USB shields.
I've opened this Mac various times in the past, last time I opened it was to replace the internal stick of RAM that seemed to be causing frequent kernal panics (and after replacing it, it hasnt panicked at all). This was about 3 weeks ago. It's been around that long since I've noticed the shocks. I thought it might have something to do with not plugging the power cord in to a grounded socket, but even after grounding it, I still get the jolts if I brush these metal parts.
So, I'm wondering whats going on here. Like I said, it's working great but I think this is a potentially serious issue. These shocks are actually pretty strong jolts. I took an LED bulb to the metal part of a firewire cable and it actually burnt....
Input is appreciated here, thanks!
