I put together a new system a couple of days ago and the motherboard is making a very high frequency oscillating whine which seems to be coming from one or more of the chokes surrounding the CPU. I can also hear this noise when my headphones are plugged in and will only stop if I disable CPU idle state through Windows 7, which isn't really a long term solution.
Has anyone else got this board and having this problem? I've read of older boards having this issue but haven't seen any recent posts reporting the problem. I'm going to RMA it but to save waiting for a replacement was going to just buy the same board again, unless this is an inherent issue on this board?
I'd appreciate any help.
