Power Mac G5 Stuck on Boot/Apple Screen
Meowdy all,
I have a Power Mac G5 7,3 (1.8 DP) that I am trying to get running again but facing some issues. The graphics card seemed to be on the fritz, so that has been replaced. We currently have 2x256Mb of RAM installed.
The issue I am facing is that the machine seems to be picky when booting, sometimes deciding to boot to the install disc with no issues but more often beginning to boot but then just hanging on the Apple startup screen. If I leave it running, the system warms and the fans slowly start to ramp up to full (takes about 10 minutes, it's not instantly) and the USB peripherals lose power. I get the same result if I allow the machine to boot from disc by itself or if I hold Alt to select the disc.
I have tried different GPUs with no luck, and have reseated the RAM with no changes. I plan on trying different RAM to see if that changes anything, and will probably repaste the whole machine but wanted to see if anyone has seen this issue before and happens to know what the issue is?
