I have to double click to do a normal left click, and in any games I play it works around 1/15th of the time. I use the trackpad. I've never had this problem until I installed windows 8.1
If it's the trackpad then i think you can configure it in the control panel>search "mouse">go to trackpad section in "mouse settings". There you can configure all the different gestures you can make with it and which one's that should be enabled.
