Caps lock intermittent affects cursor

At some point the caps lock got stuck on - the light showed. I worked out that I could use the shift key if I wanted to use lower case. Then I found that when starting up the computer the cursor was stuck at the same time, I used CTRL ALT DEL to unstick it.

Occasionally the caps lock would randomly unstick. I now have a situation where it comes on alot and if I jiggle the button it goes back to normal for a short time. When the caps lock light comes on again the cursor sticks every time...this happens every few seconds.

Wierdly it is not happening now but it does on Facebook - alot.

Any ideas anyone. (I have tried going to the settings and changing the keyboard settings. It worked for a short time and no longer does. Could this be a virus?

Thanks for reading

Hi welcome to the forum
hook up an external keyboard and see if it does same thing.
