no boot

As part of my quest to get my 7,1 to run Linux (seemingly impossible at this point) - I decided it would be a good idea to pop my OWC 4M2 into my 5,1 to see if I could install Linux onto one of those drives and then install it back into the 7,1. The 5,1 is running a fully up to date version of...

Howdy all, I was recently given an early-2008 iMac (specifically, this one) of the 3.06GHz variety. I was told that the machine had a dead hard drive, so upon receiving the machine, I disassembled it entirely, replaced the thermal paste on the GPU and CPU, then put it back together with a new...

Hey! So I recently got a PowerMac G5 and when I first booted it, just the fans where spinning but nothing else. I thought I could solve that problem later and decided to clean the Mac up, since there was dust everywhere. After I did that, I wanted to turn it on again. But nothing happened. When...
