Windows 7 - Subwoofer makes Mouse go Crazy!

**AlexRD** · 10-14-2009

Hi, i really need help.
I just bought a razer Lachesis, and my subwoofer makes it go nuts.
You can't believe how hard it was to open firefox and sevenforums :P.
What can i do to remove this craziness? Like, i didn't want to decrease DPI.

Could be many things but I would start by looking at WHERE the wires to the sub go. are they near any others. Are they shielded. Is the power outlet 3 prongs.

Then I would start looking at interference. Is the a source of RF (radio frequencies near) A cab company, baby monitor, walkie talkies, wireless IPODS, eyc

hope this helps. I will listen to that again later when I can run it thru a spectrum analyser

I had this problem too. Seemed to only occur with their drivers installed.

It would appear from your video that you are using your sub-woofer as a table on which you have your mousemat and mouse. Vibrations coming from the speaker (even the inaudible hum that is present when there is no signal) can be picked up by an optical mouse that is placed on top of it, especially if the mouse is highly sensitive. The strong (and changing) magnetic field associated with these speakers can also affect RF signals to and from the mouse (if yours is that type of mouse).

I would strongly advise that you choose a different surface on which to operate your mouse.

No, the video isn't mine. It was only for illustration, see i use it on the desk normally, not on top of the subwoofer.

And,I wanted Full DPI, cause i didn't buy a 85 $ Mouse to use it like an ordinary one
