GA-P55-UD4P posts correctly then buzzes

Ive been asking this all over and havent gotten anything yet. Im wondering if you guys can help at all:

First off, heres a link to my build: http://secure.newegg.com/WishList/ [...] r=15403048

Theres no OS installed yet. I can only enter the BIOS or get to the "please install an OS" screen.

Prior to yesterday, there was no internal mobo speaker. The system boots up fine. I can enter the BIOS, adjust settings, monitor temps and fan speeds. All fans work (including CPU). The CPU is detected. The RAM is detected and is displaying the correct speeds, timings, and amounts.

For safety purposes, I got a mobo speaker so I can hear it post. Now heres a link to audio of the problem I am having: http://www.youtube.com/watch?v=SaArOPQN8Qk
You can hear a regular post beep. Sounds normal. Its then followed by a pause and a loud squealing whine. Not so normal. Theres nothing in the manual about this and very little online.

Heres what Ive done so far:

Removed the hard drive, DVD drive, and wireless adapter yet it still made the buzz after the post beep.
I removed the graphics card and got the "graphics card error" post code which was then followed by that same buzz.

That leaves only the mobo, CPU, HSF, and RAM.

I reseat the RAM last night and still have the issue. I also tried both sticks of RAM, one at a time. Still happened.
One thing I saw after I bought everything was on the mobo RAM compatibility list. I bought GSkill F3-10666CL8D-4GBRM and its not on the list. I was told that shouldnt be an issue because the specs on the memory were correct and compatible and that brand of memory probably wasnt tested in the mobo yet. It is, however, listed on GSkills website as being compatible with the P55 UD4P

I reseat the CPU and HSF this morning but it still made the buzz. My temps idle around 36-38C.

A friend suggested that I mightve received a bad mobo speaker thats particularly noisy for no reason. He suggested that I find a PC with a speaker already in it, listen to it post and then replace that speaker with the one Im using in my PC and listen to it to see if it posts correctly and then makes the buzz.

I also came across this thread on another forum: http://forums.tweaktown.com/f69/ga [...] ing-29196/
I have a different mobo than that one but could the problems be the same/similar? I cant test it right now but do you think theres a chance that this issue is carrying over to other Gigabyte mobos?

The only options I have left are:
Check the speaker to make sure its not faulty.
Check my wiring. I did some cable management recently so maybe the wires are pulling and not giving the mobo the power it wants/needs.
Get new RAM thats on the compatible list
Replace the CPU/HSF
Replace the motherboard

The fact that I can find so little on this issue makes me want to troubleshoot the hell out of it so I need any suggestions I can get. ANy help would be great. Thanks.

You, my man, are a genius. Thank you, thank you, thank you!

I disabled all of them, sound went away.

I then re-enabled one at a time. The culprits are System Fan 2, System Fan 1, and Power Fan.
With the case I am currently using, all of the fans (other than the CPU fan) connect directly to the PSU using 4 pin molex. I guess the mobo was detecting that there were no fans connected so it was giving off an error. I guess its safe to leave these disables since there isnt anything there.

Seriously, I cant thank you enough. Its been driving me insane.
