Windows 7: Typing issue

I have a problem, sometimes I cannot type at all . I start typing it will type the 1st letter & maybe the 2nd and then stop I have to move the space bar forward type the next letter (sometimes it works & sometimes it doesn't)
I then have to backspace it to finish the word this happens predominantly on the web when typing into a message board.

Go to device manger (type that in search). Look for yellow warning by keyboard driver.

If none, go to the webite and update driver.

Do you know if the keyboard is messed up? Try booting up using ubuntu or knoppix on a dvd to see if the keyboard is responsive.

If it just started use System Restore to go back before the problem began.

No problem with keyboard drivers and it started happening about a 2 weeks ago so too far gone to do a restore

Restrore can go back several months. Your documents will not be touched, only the OS.

what happens to my windows updates if I go back a few weeks?

could it be my wireless connection keyboard is logitec with setpoint program

Updates will be lost. But within a short while you should get them again.

ok thanks
