Typing Lag/Missed Letters

Ok I have a Alienware M17XR2 laptop. I just installed windows 8.1 from a formatted start. Got most of the drivers functioning. I have an unknown device which I will address in another thread. Anyway my keyboard lags sometimes while I am typing fast. Never did that on my Windows 7. I'm running 64 bit as well. Any suggestions?

In my experiences laggy typing has been due to spyware or java intercepting my keystrokes for whatever reason.

Run spybot search and destroy, its free..

Boot your computer in safemode with networking, if no lag then its a program intercepting your keystrokes.

If still lag, you may have hardware problems, either keyboard or motherboard, possibly even video..
