Windows 7: Shift keys not working with certain letters

Hi. I browsed some other threads concerning this problem, but none of those solutions has worked for me. The problem affects only the letters z,x,c,v, and the numbers 1,2,3,4,7,8,9,0. I can't make an uppercase version of those characters. When i launched the on-screen keyboard, I see the shift keys lighting up when I touch them, so it isn't a matter of physical damage to the keys... I went into the device manager and uninstalled all the keyboard drivers there - at least I think I did... and they just came back with the same problem... And i plugged in a Logitech keyboard and its drivers worked just fine. So short of wiping the entire drive with a fresh install of Windows 7, what can i do? I had to use the onscreen keyboard just to type the question mark. Thank

What language is your keyboard layout set to?

English. I tried French just to see what would happen. But definitely English.

Does your keyboard have a Function (often labeled Fn) key to toggle certain keys for use by something like a multimedia program?

indeed it does I'll fool with that a while and see what happens. But did you have a specific idea how it could be involved ?

I looked over all the extra functions on top of the keys and can't imagine what I did to screw things up. Hope you have something up your sleeve!

I had this exact same problem and the cause were the Play/Pause, Stop, Rewind, Fast Forward buttons where the multimedia functions are (volume, mute buttons etc) . I have a Logitech Media Elite keyboard.

After i cleaned the keyboard using my own special technique everything was fine, then i tried to reproduce the problem and held in some of the media keys that don't have any apparent effects (for example, if the Mute key was stuck i would have noticed it) like the Play/Pause, Stop and Fast Forward/Rewind buttons and tried to use the Shift + letters that didn't work last time and the same thing happened. So unstick the button and clean your keyboard.

You try to help someone out and you don't get any replies, meh.

yeh I know - happens to me all the time in other forums. I got a "new message" notification this morning, but none for your other message and none for a lot of earlier messages in the thread. Woops. Thx though. Turned out to be a broken keyboard after all. 15$ replacement. I used evas computer parts on ebay. Santa Ana. Drove to their warehouse to pick the part up. I can recommend them.

Hey, Solinari.

Just wanted you to know that your post helped me solve this problem before I even had to sign up to ask the question.

Don't know if you will see this but I signed up so I could thank you.
