Noise Issue

Hey guys, I'm currently expeirencing a strange sound coming from my Machine.

It's hard to explain but i'll give it ago.

It's a high pitched Hum which seems to come after about half hour to an hour of use. At first I thought it was the CPU heat sync, but after testing different speeds it made no difference.

It doesn't sound like a fan, it's almost like one of those alarms used to deter teenagers away from area's, only softer and not constant, it's every other second the sound occurs.

I'm just wondering if you guys could provide me with some insight on what might be the case and what I can try and do to test if it is one of these.

Thanks in Advance.

definetly sounds like a capasitor... mine does the same thing when i fully load my raid drive... quite anoying actualy.

just try different things to make it happen, like gaming/moving files or it could just be random.

if its wile playing a game and you have a high end video card, they squeel as well due to the amount of power going thru them.
