I am having the weirdest problem with my mouse and can't seem to find a solution. when I try to click on things about 1/3 of the time nothing registers. I have tried 2 different mice on multiple usb ports and still the same issue (both mice work on other pc). I tried to update the device drivers and that didn't do anything either. I'm starting to lean towards it being a motherboard issue but am not great with this sort of thing. any input would be much appreciated. thanks
