Can't type unless I click Control Key

Hello.
At the moment I can start typing then after a few characters appearing, no more characters appear on screen. If I Click on Ctrl it will allow me to type a few more characters, then I have to push Ctrl again.
This is also the same with my mouse. If I click on something it will show the right click menu and will only click as usual if I use control.
Anyone else have the same problem & been able to fix it?
Cheers

Sounds like you have a 'sticky' ctrl key.

Anything spilt on it? any obvious debris, dust, fluff in or around the key?

If all looks clear, give the ctrl key a dozen or so taps then try typing again. If it persists you'll need to have it looked at.
