Exclamation Strange behavior, I think it is the MoBo

First "power exceeded on hub port" If I connect my keyboard (G15) to my monitor's usb hub (my old Core 2 build never got this error)

Second, whenever I move my mouse (directly plugged into MoBo USB) I hear a soft beep or tea kettle noise (sometimes with keyboard too)

Very low though, I'm more worried that the MoBo can be damaged.

How do I figure out if a MoBo is damaged? RMA'ing sounds like such a hassle since ewiz is not responding to my RMA emails :(

Edit: The noise can also be described as a wine. Sig is outdated, I'm using an i7

My System Specs


The noise you hear when the mouse moves is called coil whine, and is a fairly common issue. Unfortunately, there's really nothing you can do about it, since it's caused by the motherboard's power circuitry. As for the USB issue, it could be that your old board had different circuitry supplying power to the USB port with more capacity than the current board, or that it simply didn't pop up an error. I don't think it's actually a real problem though.

I was worried sick my MoBo was damaged.

I went from an EP45-UD3P to a EX58-UD3R (essentially identical MoBos just the latter is for LGA1366)

My 4890 is dead though, water got into it's backplate and fried it. I feared the same water damaged my MoBo.

Good thing I was planning on getting a 5870, so I can stop using my 8800GT (using it as place holder since 4890 died)
