Alienware 17 Keys not Working

Hi all. I recently got a brand new Alienware 17 laptop just 4 days ago and all of the keyboard keys used to work perfectly fine before I played a game called Chivalry: Medieval Warfare on Steam. I have no idea what is wrong with the keys that don't work and I also noticed that I couldn't use them when I was in the game either. Last night I had the exact same issues with the keys not working and so, frustrated, I decided to go to bed seeing as to how it was incredibly late anyways. This morning when I woke up, the keyboard was back to normal again. I don't know what fixed it and I really wish that I could have found out what it was that fixed the keyboard, and also what is messing up the keyboard. I decided to try Chivalry again earlier today to see if everything was fine and would stay fine but it messed up my keys again.

The specific keys don't work as soon as I start up the laptop.

Here is a list of all the keys not working (separated with dashes): x - c - v - ,< - ' " - 1! - numpad 5 - right shift - numpad enter - /?

I do not have an external keyboard that I can plug in. I have tried to edit i8042prt's Start and (Default) values with regedit. I have tried to use SharpKeys to assign keys to the non-working ones (and they can't be detected either). I have both restarted and shut down the computer multiple times. I have turned off Sticky Keys, Toggle Keys, and Filter Keys. Device Manager tells me that the Standard PS/2 keyboard's driver is up to date and that the device is working properly.

I would like to continue playing Chivalry but if I need to uninstall it to get the keyboard working again, then I will. Please help me, and thank you.
