Specs: Powermac G5 2.7ghz, 5Gb ram, 256MB video card, 2Tb & 1TB hard drive I did a clean leopard install on 2TB and when I restart it doesnt see the hard drive. Also had the same problem with the 1TB hard drive. When it does comes on, stuck on the apple logo then the fans speeds up. Next day it will boot up and everything will work for a hours or so then it freezes. I unplug the internal HD then boot with the external HD. Does the same thing as above. Disconnect both hard drives and turn it on. The fold with the question mark Then I ran a hardware test and it passed Also did the swaps of the ram and hard drive, etc didnt work I’m going to try to swap the hard drive cable but I dont think it will fix the problem Thoughts? Also is the logic board or CPU failing? Has anyone taken an 2.7ghz and put in a 2.0 dual machine?

Yes it was bad rams I had a pair of ramjet ddr 1GB. No issues at all Thanks
