Hello. Since loading windows 7, I have been having peculiar problems. For no reason that I know of, I am unable to type text. eg: Explorer loads normally but will not permit text to be written. Also, on occasion, The numbers, caps and scroll lock buttons are flashing and will not respond to button pressing. In both cases shutting down the computer solves the problem as opposed to restarting the computer which does not . After shutting down, Explorer takes many minutes to activate. As this is happening every two or three days, it is becoming a nuisance.
Any help will be appreciated.
