Mouse Pad not working

Hello,

I have an Alienware 14. The mouse pad began to act weird and not work at times. I have to turn my computer on and off several times to get it to work. Does anyone have a solution to this problem? I tried to reinstall the driver already but then the light that makes the mouse pad glow stopped working and it still didn't work all he time. Right now it just kinda works when it feels like it. Once the mouse pad is working though, it will usually work till I close or turn off the computer, but sometimes it also cuts off in the middle of working.

Does anyone have any suggestions?

Thank You!!
