Odd asian characters appear in top left and freezing

Hello all,

I have a weird bug that has appeared now in 4 games. These games are
BF2142, Crysis, COD 4, and now Frontlines Fuel of war.
Occasionally it seems as if my keyboard has frozen. Then when pressing
a key i see some weird asian characters appear in the top left corner.
These characters seems to show through the graphics yet don't remain on
screen. They dissappear after a moment yet reappear if i am constantly
pressing keys.
The thing is that my keyboard has not frozen. If i press shift i will
crouch (it's my choice for crouching). I can shoot and pan around using
my mouse but not move (wsad). I have to press esc twice before the game
reacts to reach the menu where i must exit the game and restart (the
game not the computer) or else the bug continues. All the while the
action unfolds around me yet i cannot move other than crouch which i've
stated.
I play many other games without problem. This error does not always
occur yet it is frequent enough to be a problem. I play in clan matches
and cannot have this occur during this time.
Has anyone else had this occur? Do any devs have some insight?

My patches and drivers are all up-to-date.

Thank you.
