Help would be appreciated (keyboard lag?)

Here's my problem:

It seems like any game I play on my PC, my characters stop walking after a couple of seconds. Like I always have my finger on the "W" key but for some reason, I stop in my tracks every 5 seconds or so. How is that?

I'm gaming on an Alienware x(something), medium settings in about all games and I'm using a wireless keyboard, if that makes any difference.

so does your wireless conncection keep dropping out because you have low batteries or interference? If you get a wired keyboard does it do the same? Maybe try update the drivers for the keyboard?nutcrackr

The batteries should be alright, I changed them about a month ago. As for interference, what could cause it? (I'm not computer savvy, if it didn't show already)

I downloaded/installed the latest driver for the keyboard and I don't have my wired keyboard anymore.

And to answer the other question, it is not a BlueTooth keyboard.

By the way, thanks for your help guys.
