So I was excited since the quad g5 I bought on ebay arrived today as well as my 30" monitor from apple. Get it all set up. Get used to this big brute of a monitor. Press the power button on the powermac, it makes its ding, then the monitor shows a question mark inside a file, then flashes to the finder face guy, then back to a question mark. Needless to say im disappointed. But am loving the 30" display on my macbook pro, I dont even have it at full resolution and its awesome. But The powermac has two HDD's. one a 500 gig and one is a 150 gig. Is it possible it is trying to find an OS on the wrong one. Or will it search both of them? Thanks again.
