When i turn on my iMac its sounds like a light bulb struguling

Not sure what a struggling light bulb sounds like. It is very hard to describe sounds sometimes. Is it an electrical buzzing or crackling sound? Does the computer still startup normally after the sound? You have Lion so I wonder if it is a new iMac. If so, call AppleCare.

How do you silence the opening chord when you turn on the iMac?

Welcome to Apple Support Communities
I do not recommend you to disable the startup sound. It indicates hardware problems when your computer is not working correctly, so it is important to leave it turned on. What you can do is to reduce the volume in OS X.
Anyway, if you want to disable the startup sound, the easiest way is to turn off the volume in OS X.

When I turn on my iMac it comes up with the icon which I then log into. The password works and I then get the apple icon and the spinning wheel. After a minute it turns into a prohibited icon. If I log on the guest icon I get to Safari. Help!

When I turn on my iMac it comes up with the login icons which I then choose and log into. The password works and I then get the apple icon and the spinning wheel. After about a minute the Apple icon turns into a prohibited icon. However, if I log in under the guest icon, I can access the wifi and get to Safari. I really don't know what to do next. Any help would be gratefully appreciated.

Are you running any A-V? If it's an iMac 21.5, I don't think you're running Leopard, 10.5. Probably at least Snow Leopard, 10.6. This is the Leopard forum.
This article says meant for 10.3.9 and eariler, but contains some still useful suggestions.

Try a Safe Boot. Shift at the startup chime and expect a much longer time to boot. This will bring you to a login screen with "Safe Boot" in red.
Look at this as well.

When I turn on my iMac, it shows a black screen and says 'No bootable device - enter boot cd and press any key'. Not sure how to fix this.

When I turn on my iMac, it shows a black screen and says 'No bootable device - enter boot cd and press any key'.
I'm not sure what to do, I did not recieve a cd with my mac to boot it up (I ordered it online).
Also I can't find my harware serial number (I've tried many times to input what I thought it may be from my receipt). I saw that I need this number to contact apple support, my 90 day complimentary support is still valid so I wish to contact them.
I don't know much about apple products as this is my first apple computer so any information is helpful.

Hold down the Alt/Option-key at startup of your iMac to get the Boot Selection screen.
From that choose to boot into OSX.
Once in OSX go to System Preferences then Startup Volume and reset your OSX to be the default.
The new iMacs have OSX 10.7 Lion preinstalled and don't come with any CD/DVD anymore.
Instead OSX Lion includes a new feature called "Lion Recovery".

Lot's of people reporting Wifi problems with 10.7.4, but some things to try...
Make a New Location, Using network locations in Mac OS X ...

10.5.x/10.6.x/10.7.x instructions...
System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.
The interface that connects to the Internet should be dragged to the top of the list.
Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

Did you already try to reset the phone by holding the sleep and home button until the Apple logo comes back again?
If this does not help, try to connect in recovery mode, described here: iOS: Unable to restore

Fan comes on when I turn on the iMac

When I turn on the iMac, a fan comes on. It doesn't turn off. What does this mean

It might mean a lot of things: from a damaged sensor to a SMC problem. First, try resetting the SMC > http://support.apple.com/kb/HT3964 This should solve the problem if it's related to a problem with SMC settings.
If it doesn't work, it's possible that a sensor is damaged. To make sure of it, run Apple Hardware Test > http://support.apple.com/kb/HT1509?viewlocale=en_US&locale=en_US After starting in Apple Hardware Test, choose your language, mark the option to use extended mode (important) and start the test. If you see an error at the end of the test, copy it here

IMac G5 Sounds like a jet taking off

Our iMac G5 sounds like a jet taking off shortly after we boot it up and try to open any applications. Also, when we try to power down and then turn it back on, a flashing folder shows up with a question mark and finder icon. Any ideas out there?

If you have not already, reset PRAM

and if that does not help, reset SMU (power management)

New 27'' Imac fan sounds like jet engine

Hi all, i am having some serious issues with my attempt to enjoy apple computers. I am a first time user coming from pc's, just due mainly to the price difference. I just got my first apple computer, a 27'' imac (the standard one, no bells and whistles for this struggling college student). Just want one mainly for recording music and doing research papers. Had to get the first one replaced due to a bad optical drive in the first day. Just brought the replacement home and after 2 days i turn it on and it sounds like a 747 is taking off in my bedroom. I am not the most computer savvy person around, but looked up as much as i could on forums. Tried all the resets and nothing works. Everytime the computer is on there is a turbine that also comes on. I downloaded the istat widget thing and it says my cpu fan is running at over 3000 rpms. I'm no air dispersment specialist, but to me that sounds high. Does anyone know if this is common as of late, and any possible fixes?? I have an telephone appointment with an apple guy tomorrow, but am pretty sure it is going to just turn into a "buy the 3 year $170 applecare plan" speech, like when i called for the disc drive.
Second, are apple computers poorly made?? I know it's wierd asking on the apple website, but i have to get some answers. 2000 dollars is alot of money to me, and the fact that i've had 2 problems in less than a week's time scares me. Should i keep trying to get a good imac that won't crap out, or should i buy something else? Thanks in advance for any replies, i really appreciate it.

Thank you guys for your comments and suggestions. I really appreciate it. I'm thinking of taking it in for repair or replacement. My only concern is that this is 2 times in one week i've had to go and get it replaced. And that's brand new. What is the reliablity for this product going to be in 6 months to a year. For 2000 dollars i don't expect to have to do that. Also apple is not paying my labor to repackage everything, take it down 5 flights of stairs, go to the inconvinently placed apple store at the center of an outdoor mall, pay for my gas, or for my time that i could be using to do something productive. I guess maybe i'm just frustrated, but still. Now if i get a new one i may not be able to enjoy it as much because i will just be waiting for it to break down. Maybe i'll just cut a flap in the new box so i can see the screen and a few holes in the back of the box to run the cables. Then when it breaks down i can just close the flap and push the cables back through, and have it all ready to go back in no time flat. Thank you again for your suggestions, i'm just very ticked off right now.
