I have a Microsoft 3.0 Intellimouse and it likes to randomly shut off. What i mean by that, the lights shuts off and my windows XP makes that beep noise. The mouse turns off and on repeatedly and sometimes it won't come back on until i unplug the USB and re-connect. I am running the mouse directly into the USB port and i've tried switching ports but that doesn't do any good. It gets REALLY annoying when this happens, I play cs and i have a CAL match today...i really need this Any ideas?
