Hi everyone,
I've been reading a lot of posts on here and decided to sign up to post my problem. Hopefully someone can help me out.
I've got an old G4 power mac (i think that's what it's called, it's the tower one with a big apple logo of the side), which has been used daily for a good five years without any issues at all.
We've recently replaced it with a new iMac so it hasn't been used for a few months. a few days ago decided to switch it on and run some OS and application updates which all carried out without error.
A few hours later however it wouldn't start up. I opened the case up and noticed that there were three sticks of RAM in there:
2 x 512MB
1 x 256MB
yet I knew for a fact that the system was originally showing the installed RAM as only 1GB. I suspected the OS updates somehow didn't like the rogue RAM and I removed it.
The system started up much faster than it used to and all was good.
The next day it wouldn't start up again. It gets to the white screen with the grey apple logo then cuts dead. All the usual start up tone and what have you are fine up until you get the Apple logo on screen.
I moved the RAM into different slots as I seem to remember it needing to be in pairs in the right slots (I've tried all combinations since), and the system booted straight up.
Again a few hours later it wouldn't restart. I switched the RAM again and it successfully booted up until I tried to restart it again later that day.
I've had it boot up ok, then freeze on the desktop at random times, but generally it just won't start up once it gets to the Apple logo.
I remembered that after moving the RAM around I'd get an error which said the clock was set to a day earlier than it should be. So I looked into this online and it led to a suggestion to press that button on the Motherboard.
Having pressed the button and waiting the 10 minutes someone suggested, it resulted in a successful boot! I thought everything was fixed as I restarted the machine multiple times successfully. Then the next day it wouldn't start up again
Does anyone have any suggestions to help me please?
