Hi, I have one of the first generation Intel Xeon Mac Pros (quad core, 2,66 Ghz I think). and in the last two days, I've been having some problems on startup...the power comes on, but the system never starts. If I turn the power on and off a few times, I can eventually get it to work. Is this something easily repairable? My Apple Care ran out and I didnt renew it. If this is a costly fix, is it possible to buy a *new* bare bones mac pro and just swap the hard drives from my first one? I looked on other threads with similar issues, but they all seem related to the NVidia 8800 crd, but I have an ATI X1900 installed by Apple. Thanks for any advice you can give me!
