So this is kind of odd. I came back to my computer after watching a movie, turned on the monitor and decided to take my left hand (in retrospect, this is probably a bad idea) and wipe the dust off the screen, while my right hands index finger was placed firmly over my mouses left click button. I received quite a shock in my index finger, and now my left click button no longer works? Doesn't that seem kind of weird. I have reversed the settings so the buttons work backwards for now.
My mouse is a Labtec optical mouse. PS/2
I've also had past experiences with my mouse where the cursor won't move after a restart. The cursor is there, but the mouse doesn't move and the buttons don't function. It's been a while since I had this problem, so I don't know if this attributes to that. Also, a few instances where the mouse works properly, but the scroll wheel doesn't. But what a strange coincidence with the shock I received. hmm.. I hope someone can help me out.
BTW, I already tried uninstalling from the device manager a few times.
