I just bought an Ideapad y510p and it came with windows 8.1

Everything works fine, but sometimes my mouse and keyboard stop working correctly.

The mouse starts moving by itself, clicking as well. And the left click acts as the right click, if i press shift it will act normally. And I can't write with the keyboard, suddenly instead of writing, it starts using shortcuts, as if I am pressing the Shift button.

What is wrong? How to fix it?

This sounds like a hardware failure. –  Ramhound Jan 7 at 3:34
