Recently, I was given a laptop from my older brother. It had a few games on it as he used it often but now doesn't. I have connected a mouse of my own to the computer and it can function -almost-, you see, my mouse can't left click for some unknown reason. I can sometimes click with the left but never very often.
Please help
(if it helps the computer is a relatively old 2011 dell laptop that had windows 7 and was upgraded to windows 8 pro)
Thank you
