Keypad/mousepad not working properly.

Sometimes when i boot my laptop, the first thing that appears is: lenovo icon with the description 'to interrupt normal startup, press enter'
This happens most of the time. And when i pres enter it goes to mcafee screen after which it goes to blank screen again.

Keyboard's blank spacwe doesnt work most of the times and sometimes it keeps pressing the blank screen without even pressing it once.
