So normally, when you press ctrl alt del you get the task manager. But when I press it, and I'm sure the keys are not broken, nothing happens.

I used a virus scan (Norton 360) but it found nothing.

How can I fix this?

- I use vista 32 bit -

I know how to open the taskmanager in a different way. But it's kinda usefull to use ctrl alt del when my computer freezes. And I think it's just weird that it doesn't respond.
