Well, it looks like the shine is wearing off my prize pony of a purchase. I got an iMac G5 a month or so ago and it appears the hard drive is already toast. That, or something else has gone catastrophically wrong somewhere inside my pretty machine. Here's the issue: 1) Won't startup properly. All I get is either the blinking globe or the blinking system folder with the "?". 2) It makes a whiny sort of squeaking noise in short bursts as I think it looks for the hard drive to spin up (sort of sounds like a really wussy alarm clock). 3) When I boot it up from the install disk and run the disk utility, it shows a Maxtor CALYPSO HD, but won't let me run repairs on it. 4) After re-booting it, zapping the P-RAM and running hardware tests, I'm at a complete loss as to what to do. 5) I spoke with an Apple rep via chat and he advised be to back up my data if I could. Anyway, it sounds like this is something awful. I'm wondering if it might have something to do with the third party RAM I installed last month. Also, prior to this issue the computer was running really well. It was only after I added another account to the machine and left it on for two nights in a row (no sleep) that I had this issue. Anyway, I'm wondering if I just ran this thing until it couldn't take it anymore but the Apple rep said that was unlikely. Anyway, I'm going to remove the 3rd party RAM I put in it to see if that makes a difference, but aside from that I don't know what to do here. Any ideas?
