Both my control keys don't work. I can neither use them to select multiple files nor use Ctrl+Alt+Del. The basic Ctrl button doesn't work. Please help!

What operating system? – RJFalconer Nov 7 '10 at 10:41

Could be an application problem or a hardware problem.

To rule out sofware, try using Ctrl with the onscreen keyboard

Start, "osk"

Do you have another keyboard installed?

Do you have any accessibility settings enabled? (Ease of Access centre in control pannel)
