Sadly, you've told us nothing of your computer, the operating system, or what you have tried. We need to know all three. We also need to know when this started. What changes were made recently? Have you scanned for malware? Did you try an external keyboard?

This laptop is a Compaq Presario CQ42 on Windows 7 32 Bit.

I've tried uninstalling it then reinstalling it. An external keyboard (which I'm using now) works perfectly on it. It started three days ago when a small droplet of water had dripped onto it from my glass. I wiped it up straight away but I don't think it did any damage.

My latest download was a Touhou game from fileshare. But my keyboard was fine even after downloading it.

Tip: Water conducts electricity. And if it conducts the wrong voltage through any of the thousands of delicate electronic components inside your computer, it can cause instant, permanent alteration of that component. (Think melted super-tiny wires).

I agree completely that electricity and water don't mix. But a single drop of water should not have damaged your motherboard like this. My guess the water drop is a coincidence or some water got underneath and tangled with some dust and debris and is lodged somewhere causing havoc. If me, I would use compressed air or a can of compressed dusting gas, turn the notebook upside down and start blasting away. If using cans of dusting gas, take care to avoid spraying liquid.
