    When I boot up my computer all is fine. It will work fine for an hour or two. Then for no apparent reason it begins to act up. I use Chrome as my primary browser, but the same thing happens in Edge. When I click on a link that opens a new tab, the tab opens behind the primary webpage. Scrolling no longer moves me up and down a webpage, but shrinks or enlarges the text. If I try to type in a text box, no letters appear but the computer acts as if the CTRL key is pressed. If I type V it pastes the last phrase I copied. If I type U it jumps to the source code for the page I'm on. If I try to open Word 10, I get a pop-up saying the CTRL key is pressed and do I want to open in Safe Mode.

    What I have tried so far. Reboot (when in doubt!). If I reboot my computer it behaves normally for an hour or two and then reverts to thinking CTRL is pressed. Run the Troubleshooting hardware diagnostic (no impact). Sub in a different keyboard and a different mouse (no impact). Change scrolling feature in Chrome (seemed to work at first and then reverted, but maybe I rebooted. I forget.

    This is very annoying. I'm on my laptop at the moment, because my desktop is acting up again and constantly rebooting so I can continue to work is not good. Any suggestions?

    Correct me if I'm wrong, but if you plug a keyboard into a laptop, the actual laptop keys continue to work. Unlike a desktop where you would remove the suspect keyboard and replace it with another. So it's entirely possible there is an issue with the keyboard/CTRL key of the laptop.

    The problem is not with my laptop, it is with my desktop. Since I have the same problem with two different keyboards, it seems most likely the problem is not with the key or the keyboard. The 2nd keyboard that I swapped in had no problem on my husband's computer, but developed the same issue within an hour of use on my desktop.
