    When I type, the keyboard does not always respond. I can fix it by unplugging the keyboard cord from the computer and then plug it back in. I bought a new keyboard, and the problem is still there. The mouse works, the keyboard works, so what could cause this intermittent problem of the keyboard not responding?

    Have you tried checking the terminals (dirt, plastic, loose) have you blown in the USB ports to see if there's anything obstructing the connection? Have you tried a different USB port? Have you tried a different keyboard in the same port? etc. etc.

    This suggests a problem with the USB port on our computer; try plugging the mouse into the USB port that currently has the keyboard plugged in (obviously, take out the keyboard first) - if mouse becomes unresponsive then you know that it's a USB port problem (on your computer), so you could take it to an Apple store - even if you're out of warranty, or don't use that USB port.

    If the mouse works fine whilst in the potentially faulty USB port then plug your keyboard into a different USB port, if the problem continues then you know it's not a problems with the ports on your computer. (To verify).

    The next stage is to check the keyboard connections for loose wiring, or fraying of the cable - it is possible that you were unlucky twice.

    Then, if possible, dual boot with another OS (xp, Windows vista, Windows 7; there a 30 day activation 'trial' with Windows 7, so you don't need to purchase it for this little test; if not, you could use ubuntu), and (using the same USB port) see if the keyboard is still unresponsive. If it is, then it's a problem with your keyboard; if it's fine then it's a problem with the Mac OS X *driver*.
