Alienware 17 R1 Keyboard / TouchPad Issue

Hey guys i have been experiencing a problem with my laptop i have changed all ribbon cables even both touchpad and keyboard same issue.

1) RGB light on keyboard doesn't work and even on the alienware logo and back cover the alienware skull also doesn't show red color when i change it from alienware command center certain colors doesn't light up e.g Red
2) sometimes touchpad and keyboard won't work they are not detected in the system.
3) mostly both of them work but also on touchpad the RGB light won't glow on touchpad while using it.
4) when keyboard is detected it doesn't work properly, when i press some key like '' Z'' it would type Spaces before "Z" so the result would be like" Z" space and then Z similarly if i press "b" it would print "BM" together even though i only pressed B
So basically i press some key another key is pressed along with it.
