I just built a new computer this past week. Everything was going very smoothly, all OS and software installed and running fine, until this morning. I just moved into a new apartment, got everything set up, then ran my old computer, which is an old power mac G5, in target disk mode in order to transfer some of my files to my new PC such as songs, documents, photos, etc.. It seemed innocent enough except as soon as I plugged in the firewire cable it was LIGHTS OUT for my brand new computer, it was instantly gone.
I saw no smoke, smelled nothing funny. The computers were plugged into the same Furman rack mounted power supply. Nothing really seemed out of the ordinary except that the new computer went out. I disconnected the mac and tried to boot the PC again, there was a small click but nothing. If I waited another 10 seconds or so, re-flipped the power supply's rocker switch, I could get it to reproduce the click again but nothing more.
At this point I was nervous, and rightfully so. Was my Mac reaching its hand out of the grave for one last hurrah at me...cursing my lack of loyalty? Perhaps. Is my new apartment's power faulty, causing some weird power surge for my two computers? A little more likely I suppose, although it doesn't really make too much sense if they were plugged into two branches of the same exact outlet.
I opened up the case and tried the power again to determine the source of the clicking. On the motherboard, the CPU fan is beginning to turn but stopping almost instantaneously. At a similar rate, a few LEDs on the motherboard flicker once (I think they're green and yellow but its so fast I can't even tell).
I should note that it is a Gigabyte Motherboard and Antec 450W PS. I will be able to borrow or buy a PS tester and can check that.
My guess is its either the power supply or the motherboard (i'm hoping for power supply). If I'm unlucky its both. If I'm really unlucky its all of the components! Please help! Yargh!
Thank you again! Nick
