Ctrl [left\right] + Space

Ctrl [left\right] + G

Ctrl [left\right] + H

Ctrl [left\right] + Alt [left]

Ctrl [left] + Insert

Up + Left (yes! just two keys)

and some others that i can't notice it until now ...

Can anyone help me to understand what problem was occurred?

Update 1:

I`m using win 7 SP1 x64 and problem is Global in every where after my little brother punched my keyboard.

Beep sound can be heard trough the speakers not main-board anytime.

Ctrl [left] + Home

Ctrl [left] + Delete

Ctrl [left] + Page Up

Update 2:

Please add information on which operating system you are using and in which applications the sound occurs. –  Tim Sep 11 '13 at 12:13
    
You say it beeps. When it does this is the key recognized (eg, in an editor) or is it ignored? In any event it sounds like a stuck key. Have you tried rebooting (on the off chance that the "stuck key" is purely a software mode switch)? –  Daniel R Hicks Sep 11 '13 at 20:56
    
And have you tried "punching" the keyboard again? –  Daniel R Hicks Sep 11 '13 at 20:57
    
(Is this a separate keyboard or one built in to a laptop or whatever? Wired or wireless?) –  Daniel R Hicks Sep 11 '13 at 20:58

1 Answer 1

One of the keys on the keyboard may be stuck. Open up a text editor so you can see the result of pressing keys, and start pressing each key in turn. You may not see anything unusual when you press the stuck key - pressing it may just cause it to become unstuck. Or you may find that you are unable to press the key because it is stuck, which will identify for you the key that is the problem. After you've tried all of the keys on the keyboard, try the problematic combinations you listed above again and see if the problem has been resolved.

I've found that some software can cause my keys to become "virtually" stuck - the Windows Remote Desktop tool does this to me sometimes. After switching back to my desktop from the remote desktop, it acts like I'm holding down either the Windows key, Alt key, or Ctrl key. Pressing each of these keys fixes the problem.

Thank you man. I`m tried that way you said but problem is still available :( ... can it be due to a hardware error or something like that? –  Victory Hymn Sep 11 '13 at 19:05
