Ctrl [left\right] + H

Ctrl [left\right] + Alt [left]

Ctrl [left] + Insert

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

Can anyone help me to understand what problem was occurred?

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
