I just upgraded to Windows 10 after all that hype but it looks like I can't even play games or do any work on PS or AI. Whenever I hold down a key on the keyboard, the mouse cursor freezes and I can't move it unless I let go off the key.

I have updated my drivers and everything, but I am not able to fix it. Someone help me? I am on an ASUS G75 laptop btw, using in-built keyboard and external ROG mouse that comes with it. Tried the issue with touchpad too, same problem.
