I am having trouble with moving my cursor. When ever I hold down any key, I cannot move my cursor around on the desktop, but I can move it if I hold down the CTRL key. I have a Synaptics PS/2 Port Touchpad and a Standard PS/2 Keyboard, & I have a Windows 8.1 HP Laptop. I also had a similar problem like this before, but instead of not being able to move my cursor, I was unable to click. However, I am able to click while typing, but cannot move the cursor. I am not sure when the problem occurred or how it happened.
