F-keys not working

what would cause the F-keys to stop working, like F1 F2 F3 and so on, none seem to work

oh im on XP fully updated, using a logitech keyboard

 

Have you tried checking the f-lock setting? Some keyboards have a button that has a switch that allows you to toggle the f-keys between the f-keys and multimedia keys.

The f-lock should just be a button on your keyboard.

 

how do i do that?

 

well, there are these things on keyboards called an f lock.

It should be something like in this link

If you don't have that, I suggest doing what TxTazDad suggested and try another keyboard

 

yep that did it thank you very much
