Well I got a wireless optical mouse and keyboard combo and it comes with a sensor and a CD. I think my brother installed it because when he was using it, it was working fine. After he leaves though, I turn on my computer and it doesn't work. My keyboard works fine, but my mouse isn't.
I think the problem is with the installation because when I move my mouse the sensor blinks, but the pointer doesn't move. Same thing when I click.
Also, when I start up my computer my mouse stays off. I have to take out the battiers and stick them back in for it to work, and yes they are good batteries, I recharged them overnight.
My mom is gettin' mad that i'm using her computer, so please help.
