Hello so yesterday morning i woke up and i got on my laptop. and realized my keyboard stopped functioning so i restarted it mouse was working but the keyboard only worked for a second after the windows startup. so i formatted the computer again to windows 8.1 after installing few software's and drivers my computer went for a restart. when the system started up. the keyboard had stopped functioning again. at first i thought it was because there was some sort of virus in my files that i had transferred back on my computer. later i downloaded latest version of windows 10 installed it on 2 computers my brothers and mine. it seems to work perfectly fine with my brothers computer... after installing it on my computer the keyboard was working and running smoothly  until i installed the windows update which gave problem with my graphics card driver and i thought it was because of my wireless card disconnected from internet. so i restarted the computer and again i'm stuck with a non working keyboard. and yes i have also checked ease of access.
so i don't know anymore what to do please help me? is there is problem with Nvdia gtx 780m graphics driver or is there a windows update causing this? 
i'm sorry for the long paragraph. thank you for your time.

Have you tried another keyboard?  You can plug a USB keyboard into the ports on the sides of the laptop.
As the problem occurs in both 8.1 and 10 - I'd have to wonder if there's a physical problem with the keyboard.

My browser caused a flood of traffic, sio my IP address was banned. Hope to fix it soon. Will get back to posting as soon as Im able.
