1 Beep and takes Multiple attempts to Start

Hello i have a IMac 21.5 Inch Late 2009 and i Installed Fedora 11 on it (What a stupid think to do i know). Ever since i did that i get a Long Beep on Startup and have to Keep Trying to Start it up after about 3 - 5 Attempts at Shuting it down and Switching it back on it after a couple of attempts. Comes on and Boots up Like Normal to a Mac Operating System. Also its a Black Screen and the Beep only happen's once and not every single time i attempt to get it to bootup like normal. But i have to keep repeating the process to get it to boot up after restarting it, shuting it down etc. Please can someone help me! What i have tryed:

1.Reseting the Computer & Erasing the Hard Drive

2.Command, Option, P and R

3. Even installing Lion and getting the updates

What i have to do:

1st Attempt: Starting it up Getting 1 Bleep and Black Screen. So i shutdown the computer by either Plug or Holding in Power Button

2nd Attempt: Starting it up Getting a Black Screen and no Booting to the OS. So i shutdown the computer by either Plug or Holding in Power Button

3rd Attempt: Does the same as 2nd. So i shutdown the computer by either Plug or Holding in Power Button

After doing it a couple of times it Boots up like normal

iMac, Mac OS X (10.7)

Do a SMC reset, this may take 2-3 times. Please read and follow the instructions carefully:

SMC RESET

Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.

PRAM RESET

Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

As for me, I've found a (sort of) workaround - I just suspend my iMac instead of powering it off. And I rarely reboot it - only when updating the kernel. When you have to reboot it you can find the right timing of pressing the power button (it's harder to explain than to try) - if you power it on and then press the power button again in a second, you can save time of waiting for the iMac to power off - it will turn off immediately.

I've been doing this for the past four months, I'm going to take the old girl into Apple and pay a ridiculous fee to find out I have to pay another ridiculous fee to fix it.
