Irritating noise, please help

[VortX]

Hello, I have only just recieved my compents yesterday. since then I have been running multiple program and tests. However I have been hearing some strange noises coming from the system. I can't identify exactly what is making the noise. The noise is very faint when for instance scrolling though Windows startup menu, but when I run 3DMark06 the noise loudends and sound like a squeek/hiss. I am getting really annoyed with this sound now. Please, pelase help me figure out what is going wrong. (This noise is with and without stock clocks)

System specs:

Asus Commadno
Intel E6600
BFG 8800GTX
4GB Crucial Ballistix 5300


I think it must ne one of the above compenetns because that is where the sound is coming from. Again I ask for help, this is realy anoying and worrying and I don't want to properly OC it until I can figure out what it is?

Yeah I think its the GTX. If I get a chance tomorro I will swap it with a 6800GT and see if it is that. I am pretty miffed though. I buy one of the most expensive GPU's in the world and it is the only thing in my system that is having bloody errors lol.
