I don't think that this keyboard has that key built in.
Have a look at Gadwin PrintScreen for capturing screens or active windows (and other features). The default hot key for this program is "print screen" but can be redefined.
You could also use the on screen keyboard.
Windows XP comes with a built in on screen keyboard. Basically a graphic of a keyboard comes up and acts like your keyboard, you can use your mouse to hunt and peck around. What uses does this have and what did I use it for? Well, it's good for people with disabilities, where it would be easier to use a mouse than trying to type or it's great to use when your keyboard goes loco on you. Yes, we've all had our keyboard go nuts. Here is how you launch it:
- Click "Start" button - Click on "RUN" - Enter\type "OSK" (without quotes)
The keyboard comes on
You can also create a shortcut to the "On-Screen Keyboard", because if your keyboard should go out on you, it would be handy to have it. All you do to create the shortcut is to:
- Right click on the desktop - Click the new shortcut button - Enter\type OSK, click next twice, and there you have it.

There is no NumLock key on that keyboard. But you can switch it off by accessing the Windows on-screen keyboard. XP - Start - all programs - accessories - accessibility - on screen keyboard. The keyboard appears on screen with a NumLock key. Vista - smiliar commands to get the keyboard up.

When you replaced the keyboard you could have dislodged the video connector/cable. This connector would be located near the top edge of the keyboard. Remove the keyboard and check the video connector/cable, remove and insert the connector again then install the keyboard.
