Solved windows 8.1

Since upgrading to windows 8.1, my laptop keeps locking, it doesn't matter if your typing a letter, reading emails or browsing the net, it just locks up. Sometimes you only need to touch a key on the keyboard and it will lock. What can I do to fix it

I would check for driver updates.

I second Winuser's suggestion. You need 8.1 or 8 driver's.

Thanks for your help, I updated the drivers and it seems to be working fine now
