Water poured on your system or on the keyboard and mouse?
Is it a desktop or a laptop.
If it is an external keyboard & mouse for a desktop, replace them. New ones are not expensive. (working used ones are dirt cheap)
If it is a laptop, get it checked out and blow-dried immediately. Retained water could cause major damage later.

Disable its driver! Go to the keyboard properties.
