Hi guys. I need some help. I have an iMac G5 that seems to be having some serious problems. It is a 17" 1.6 Ghz w/ 1GB of RAM.
The problem:
• When I press the power button, I get the beautiful Mac chime, and the LCD turns on to the gray apple screen. I get the spinning gray bars below the apple, and then...it shuts down. Sometimes it doesn't even make it to the gray screen and it shuts down.
What I have done recently/tried.
• I installed iLife '06 and all the updates a day or two before this began.
• I reset the PRAM.
• I tried booting in safe-mode...no luck.
• I tried starting from the factory CD. The drive begins to spin, and then it shuts down.
When this first happened (yesterday), I started it in safe-mode, and everything looked ok. I zapped the PRAM, and then started it up, and once again, everything looked ok. That was last night. When I got home from work tonight, none of those things worked, and I am now looking for some help from you guys. Any suggestions? Thanks, in advance, for the help.
BTW, I think I'm running 10.4, but I'm not certain because I can't start it up to tell.
UPDATE:
I also just tried resetting the SMU. I got past the gray screen to the blue screen, and then WHAMO - it shut down. That's the farthest it's gotten today, though. Any ideas? Thanks again, AC.
