ctrl

I was browsing the web with Chrome and pressed f. A search box appeared. I then pressed s, after which Chrome asked if I wanted to save the web page.

I soon realized that my PC was thinking that I was constantly pressing the Ctrl key regardless of what program I was using.

In response, I tried clicking both of my Ctrl keys a few times to no avail.

This problem arises sporadically as I work. I am not sure what is triggering it.

Why could this problem be occurring? Is it the keyboard or software? How should I respond?
