Hello,

I have a big problem for a months. Mouse and Keyboard are connected in 2 USB ports and when they are connected I can hear noise,crackling sound and it's very annoying. When I disconnect them, crackling sound goes away. It's same when I connect usb flash drive, iphone... crackling sound!
I tried different ports but it's same...
Here's video where you can hear that sound:

I noticed that when I move mouse, noise is louder...
I don't know how to fix it.. Anybody had experience with this?
Please help me ...

My motherboard: ASUS M5A78L-M LX3

Coil whine might be what you experience that irritating sound/buzzing.
That psu is sketchy BTW.
I have/had 2 revisions of that MS PSU's, the oldest one that i have is still working in perfect condition, the newer is a bit sketchy to me cause the transformer gets hot.
