Slay, what about polling rate? There are 2 settings on the bottom of the mouse - 125hz and 1000hz. I had it on 1000hz. Is that OK? When it's on 1000hz, I notice a distant buzzing noise when I move the mouse. When it's on 125hz, it is silent.
I just have a crazy feeling that the higher polling rate is causing the problem.
Edit: I have been reading more about it and a polling rate of 1000hz uses some CPU power, so there must not be enough voltage causing this problem..?? Now raising the PCH voltage is making more sense to me.
