I am having a terrible time with my high powered machine. The keyboard is not displaying the keys as quickly as I type. Sometimes I have to wait up to a minute for the key to display. When I type ahead it sometimes loses characters.

I am not sure where to start looking for this problem. It started about a month ago and I still have not figured out why. It does not always do it. But acts up about 2-3 minutes out of ever hour of use or thereabout.

How can I look to isolate and find the problem, and solve it?

Have you tried a different known working/older keyboard yet? Tried a different USB port (if it's a USB keyboard)? –  White Phoenix Nov 22 '11 at 23:04

I'd look at the CPU temperature. And I'd try another keyboard. –  David Schwartz Nov 22 '11 at 23:54
    
Have you checked Task Manager for busy processes when it starts acting up? –  techie007 Nov 23 '11 at 1:22
