Keyboard problems
Hello. I am still running Windows 10, and over the past two weeks, my PC has been acting up. At random intervals—sometimes an hour after turning it on, other times after just five minutes—it behaves as if the Control key is being held down. A single click selects everything on my desktop or within a menu. Furthermore, clicking any program opens endless new instances instead of bringing up the active window. This automatic selection continues even after I unplug my keyboard. Restarting the PC returns it to normal temporarily, but I have already had to restart it twice today. Please help.
