Problematic iMac G5 20" 1.8ghz - 2009/08/01 19:45
I've run into interesting set of circumstances with this iMac. It's been thru the apple recall a couple years ago. New logic board, new power supply. It was running fine. Till about a week ago, I shut it down for a few days while I was out of town. Come back. Start it up. Gives me the regular start-up screen. Half way thru the start-up, it shuts off. Try again. Same deal. Do this several times. Always the same result. Try starting from the my retail 10.4 disc. It starts and goes thru start up just fine. So I did the complete repairs to the HD and restart. Same deal. Half way thru, goes dead. So start up from the disc again. Starts fine and I decide to do a clean install of the system. Do this. Starts fine. Runs for three days. Not a glitch. Pulled all important data off of it. So this morning, I shut it down again. Left it shut off for a few hours. Do start-up. Same deal. Half way thru, goes dead. So start up from disc and it starts fine with the exception of horizontal colored lines going across the screen which lessen until gone. So I wiped the drive. Zeroing it now. Going to install fresh. We'll see what happens
Now my wife, being the lil techy she is, suspects malware. That inserts itself on shut down to stop the start-up. Me, I dunno. I kind of agree. But being a skeptic I also think it may be hardware related. Anybody else had this happen? If so, what was the solution besides sell it on ebay as a broken machine?
