Q: touchpad and keyboard dosen't work

Hi,

am using a MacBook4,1

it was working properly until i pluged into a non Apple keyboard to my MacBook.

After i pluged in an error has been occurred like press the key rapidly just after the right button.

but there was not such kind of button in my USB keyboard.

whatever,an external USB keyboard works fine.

after some time later,i discovered that my built in touchpad and keyboard stop working.

now i dont know how to fix it up. even am writing it using an external keyboard.
