Odd Problem with a few games--Stuck moving in one direction...?

[LuckeyDavid]

It began when I was playing Oblivion. One day when I loaded it up, my character was stuck walking to the right. I never had this problem before, so I assumed maybe one of my keyboard keys were stuck. I unplugged my keyboard, and placed a new one in. The character continued moving to the right. I rebinded the move right key, and that did nothing. I became frustrated, so I reinstalled oblivion, got rid of any trace of it on my computer, and restarted my computer. And my character continued to move to the right.
I gave up trying to fix it, so I went to play GTA:SA which didn't have the problem. The next day, I reinstall oblivion, and oddly it worked. I played for a while, then I believe it started with me pushing the escape key. I went to get my laundry from downstairs, and when I came back and pushed the return to game button, my character was stuck moving to the right. I got very angry, and just gave up and uninstalled the game. Then this is where it gets weird, I go and load up GTA:SA, and when I load my game, I'm stuck moving to the right! I turned the game off, shut my computer down and went to bed. Then the next day, I load up GTA:SA, and my character is stuck moving DOWN. I thought maybe it was the game, so I rebinded the keys, reinstalled the game, and switched keyboard. NOTHING WORKED. The odd thing is, the problem is only in Oblivion and GTA:SA. I load up Counter-Strike Source and Counter-Strike, and it's fine. It just doesn't seem to make any sense to me.

Are you sure you've been completely rebinding the keys? Often when you bind keys in a game, it doesn't remove the action's old binding. San Andreas can have up to three keys/buttons assigned to each action, don't know about Oblivion though.

Make sure your keyboard language settings are correct (Control Panel->Regional and Language Options->Languages->Details). Also try running a DirectX9.0c installer, there may be something wrong with DirectInput.
