Have you experienced slow keyboard response? The time between key strokes and screen output, is extremely slow, even in some simple task like word processing. You type some five letters ahead of what’s shown on the screen.
There are a number of cause for this:
- accidentally turned on windows “Sticky Keys” feature
- keyboard auto-repeat delay and rate misconfiguration
- rogue process running
- virus/worm/spy bot infection
- computer overheating
The list could go further but those are the common ones. If you have some experience, maybe you could share some of the reasons too.
