I attached one firewire end into the tower's front firewire port. And then plugged the other end into my mac. The very moment the cable was attached to my Mac, the PC shut itself down instantly. The only programs running on the PC was Firefox and Fraps. Not seconds after the computer shut down the PSU begin to make a very faint and high pitched whine. I flipped the power switch located to the back of the PSU to "off". Then switched it back "on". The whine started right away and then stuttered every second. As if it was meant to be some kind of alarm. When I turned the switch back to "off", the whine increased in pitch as if a power plant was starting up. Then it finally stopped. I have since then unplugged the computer. Thinking maybe it was a problem on my part I unplugged the PSU's power cable (the one that goes into a wall outlet) and opened the PC. Seeing if just anything could be amiss. Which I sadly found nothing. Every cable is correctly in place. I even re-insterted the tower's power switch/power led/Hdd led ect plugs thinking maybe it would help. It did not. I noticed this problem on once before in a different issue. And that was when I had built this computer for the very first time. When I tried to first turn it on, it did not boot, and the PSU made a whine. I flipped the power switch on the back of the PSU 1-2 times and tired it again. For whatever reason, the PSU started no problem and has been working with out issues for months up till now.
hmm whining sounds like PSU but i donno why it would shut down when connected to mac? beats me sorry. up for some help
Well, I had to go to a shop just yesterday. The PSU and motherboard are dead.. I have to have both RMA'd. Thats like a 3 weeks process. Can anyone take a guess at why attaching a PC and Mac together through a firewire caused this? Or was it perhaps the PSU just waiting to blow..
not three weeks i did RMA's at my shop and it doesnt take that long. dont owryr it will be back in no time
Sounds like a dying PSU. Try getting a new one. I dont think the plugging the cable into the wall was the reason. I just think maybe it was just struggling but just coping. And the power it took to plug the cable in might have pushed it over the top. If it did what you said it did then that psu seems pretty pooped! lol Lecsiy
