I just upgraded my system with a new motherboard, cpu, ram, and a few other things. My motherboard makes a high pitched squealing/buzzing noise that can barely be heard, but if I put on my headphones (front panel port), it's amplified many times. It's also amplified by my speakers plugged into the rear ports. In addition, when the computer goes to sleep, it wakes up instantly, before the hdd's even have time to spin down.

I just updated the BIOS, and that fixed the sleep problem. However, the sound issue hasn't changed. If I disable C3 and C6 in BIOS, the sound issue almost completely disappears, but then my CPU remains at full frequency and voltage during idle, which speeds up the fan (I want it to be quiet at idle).

Is there any solution to the noise?
