Several days ago, my computer has developed a problem. At seemingly random times of day it will stop responding to key presses. It can sometimes take up to 5 seconds for the computer to respond to input when this is happening but I can move the mouse and click without trouble. It is not limited to specific applications and it even blocks shortcut keys such as Windows-D
How can I find the cause of this problem? Could it be a running process that is blocking keyboard input?
Dell Precision LAPTOP, running Windows 7.

You may have a program running that is intercepting keyboard strokes when you press a key.
You should run a full system scan according to the directions in this community-approved virus detection and removal wiki and make sure there are no unauthorized programs running on your computer.
I experience a similar problem due to a screen dimming program that runs in the background. During certain times of the day when it is adjusting the screen, I cannot type.
