Keyboard issues with PR

[Softy]

Specs:
Win 7
Intell dual core
Geforce GTX 265 OC
4 gigs DDR2
My keyboard is a Razer Lycosa Programmable Backlit Gaming Keyboard
Heres the url incase its needed : Razer | For Gamers. By Gamers.â„¢ | Online Store - Razer | Gaming Keyboards | Razer Lycosaâ„¢ Gaming Keyboard

Now heres my issue, Randomly playing PR my directional keys ( I use the arrow keys) sometimes force my player to a certain direction like to the right even if im not pressing the right key. Also sometimes certain binded keys stop working like IE my tab key wont work that normally brings up the score board.
The only thing that fixes this is rebooting, witch is very frustarting when sniping.
I have tried hitting the problem key mulitiple times but nothing changes.
Any input would help.

maybe your bf2 settings are corrupted... try with restting the controls to default

else:
you should install the keyboards latest drivers

maybe the keyboard is actually broken. this should be a warranty case then
