The Ctrl, Shift and Alt keys on my laptop—an Acer Aspire 7736ZG laptop running Windows 7— have stopped working; both the left and right sets of keys. I have searched for solutions to this problem but I cannot find anything that works.
What can the problem be and what should I try to fix this?

Assuming that the problem is with software, try the following :
Keyboards and Languages
tab, clickChange keyboards..
and verify that you are using the correct keyboard. (Have you got more than one?)Use the
System Configuration
utility, General tab, clickSelective startup
and clear theLoad startup items
check box. On the Services tab, click theHide all Microsoft services
check box and clickDisable all
. OK out and restart the computer.If the problem still does not occur, turn on Services back in binary search mode until you find the guilty one.
