This last week - I can't remember exactly when it started - the computer has developed a lag between the time I strike a letter on the keyboard and when that letter shows up on the screen. I don't really type all that fast, but I'm running way ahead of what is immediately visible on my screen. If I stop typing, the screen will catch up, zipping the cursor across the screen from left to right and revealing the letters.
It is really bothersome if I mis-type something because I can't see it to immediately correct it.
It happens when I type messages in Lotus Notes email,when I write in MS Word, when I fill in a form or enter a password on a website - and it is happening now as I write this. There even is a lag between pressing a directional arrow and the response in a falling piece when I take a break and play the old Tetris game.
Any suggestions for how I might correct this?
Thanks in advance for anything you might be able to tell me.
