Hi, I recently bought a 2006 Mac Pro 1,1 EMC 2113 from eBay, and it was functioning fine for a couple boot ups, but then the cursor froze. I powered the machine off, only to find that it now hung at the Apple logo with no loading wheel. The unit didn't ship with a keyboard, so I've been trying everything I can think of using 2 different PC keyboards and 2 different mice. I even went so far as to replacing the PRAM battery, no luck there. The keyboards no longer light up, and the machine doesn't seem to respond to them. I've tried a SMC reset as well, using the power button, and removing the HDD, graphics card, and memory during the reset. Might the computer respond to an Apple keyboard, or should I not bother to get one? Also, any other ideas are welcome. I have a Snow Leopard disc recently received from Apple as soon as I'm able to get the drive open, and get the machine responding to keyboard commands... Help is greatly appreciated! I have experience with PC's, but not so much with Mac's.
