Question about Apple iMac Computers & Internet
A couple times the fan has come on at the same time. I have a new computer, but want to keep this one for graphics work.
Posted by Anonymous on
It sounds like your graphics card is going. Have you tried re-seating/replacing the RAM?
Hope this helps!

Testimonial: "I haven't actually taken the computer apart to try that yet, but it might make sense. A month or so ago I was having a problem - solved by unplugging and replugging in the iMac from the back, so maybe something got jostled loose then."
a 6ya expert can help you resolve that issue over the phone in a minute or two.

SOURCE: iMAC G5 Boot problems
This sounds like the HDD hard died. Sometimes you can hit "option" at the startup to see if the HDD is corrupt. If you see a file with a questionmark in it, then you need to reinstall the OS, BUT before doing this, restart it and hold "apple T" it make the HDD and the computer a giant external hardrive. Just get a firewire cable and backup the hard drive onto another system before reinstalling.
If you see a disk icon come up, there is definate directory problems as it still recognises that it has a hard drive. Disc warrior might fix it.

If you have re-installed the RAM without any luck, it looks like you have to take trip to your closest Apple Repairer. It could be any number of problems. Video card, display, logic board. Only when it has been diagnosed will it be known. If the computer is less than 10 days old you can ask for a new one. Yours would be classed as DOA. If not, standard warranty it 12 months from the Invoice date.
Hope this helps

same thing happens to me - most of the time it will just randomly freeze; occasionally i get an unresponsive black screen. this 24' aluminum imac usually has startup problems also - sometimes it will "gong" and nothing else; sometimes the apple logo will come up and then nothing else; sometimes it will load the logo and then spin for a few seconds and then freeze - the only option is to manually shut down. there is no rhyme or reason to it

Sounds like possibly the motherboard has thrown in the towel.
1 thing to check is did you apply new thermal paste to the processor before putting motherboard back in?
Did you make sure all wires were seated as you pushed motherboard back in?

Is your screen image also magnified?
It sounds like you accidentally zoomed the screen, which you can do by holding down the control key at the same time you are rolling the wheel on the mouse. When you do that, the screen will follow your mouse so that you can access portions of the screen that have "zoomed off."
Hold down the control key and roll the mouse wheel until you have zoomed all the way back in. Alternatively, visit System Preferences / Universal Access and modify the Zoom options to suit yourself.
