Power Mac G5 video only comes on in Safe Mode
Posted on 2010-09-17
Hello folks, first off, I'd like to say that I'm a PC guy with little to no knowledge of Macs, but have been put in charge of a computer lab at college/work where there are Macs. Having said that, I'm having problems with a Power Mac G5 in that when I push the power button, the power light comes on, but no chime at all. If I leave the computer to boot normally, it will boot up to the point of the gray apple screen with the turning/loading icon, but after that, the screen goes blue, and all I see on the screen is the mouse cursor. I have it connected to a Dell 15" monitor (just for testing).
When I boot into Safe Mode, everything works fine, and the video comes on with no problems. I am able to log into my account, and use the computer without any problems. After opening the system profiler in Safe Mode, it shows these specs for the computer: Dual PowerPC G5 1.8 ghz processors, 1 GB (2-512mb) ram chips, GeForce FX 5200 video card, and there is no built in audio (which is why I probably don't hear the chime at startup). The OS is OS X 10.5.8
I have tried to use the AHT disc to do a scan of the hardware, but it will not load the program even though I am holding down the D key; all it did was hang at the gray apple screen with the loading icon turning, and then the fans started reving up to max. Tried to do the PRAM re-set, but that didn't work either. Could someone please adivise? Thanks in advance.
