Q: Why does my iMac G5 beep three times and put fan on full blast in stead of booting?

My G5 just issues three loud beeps and puts the fan at full whack in stead of booting normally. From time to time I have been lucky and it has started up, but next time it's the same again...

I'm worried it will never start up again!

Kind regards,

There appears to be a problem with the computer's RAM. Remove and reinsert all of the modules, or try using different ones.

Hi Niel,
You're going to have to tell me how to open the thing... I'm not a novice technically, but I haven't had this thing open before. I can see three cross headed scres at the bottom, but that's all, and nothing seems to happen when I loosen them...

Check Crucial's or OWC's website for RAM installation instructions in your model.

As I said, I'm not totally lost technically.... I managed to get it opened and have picked out the rams and put them back in. They are Crucial BP 112T6.TR RAMs.

I'm asking the moderators to move your post to the iMac (PPC) discussion area.

Are the three beeps running for about 1 seconds each? If they are, the hard drive in the iMac may have failed.

Ouch! What do you suppose is the reason that the machine has started on occation? Maybe a bad connection to the HD? Since I got a Macbook some yeras ago the G5 has been stationary for extended periods. This may add to the problem too, by letting the connectors oxydize. My experience when it comes to connectrors in cars...

I'll give the connectors a good clean and try again!

Cheers!
