Wireless Keyboard help

[RobertoIsRad]

So I've got a microsoft wireless comfort keyboard v1.0a. My problem is that while I'm playing a game sometimes the keys will give out. Like if I walk forward for awhile the w key will "undepress" by itself or I'll be crouching and I'll stand up all by itself. It's always really random when it happens and it happens with every game I try. I've updated to the latest version of intellitype and I've tried connecting and disconnecting dozens of times. If anyone could help it would be great
