Whens the last time you ran a Windows Update?
You need the drivers for the hardware and they are preinstalled with XP for your particular model.
Go here, and download them:

Connect the camera and lets see if it picks up at all. Do you have a spare USB cable to check with (as the one you have maybe faulty)?
Anyway, if after installing drivers and connecting the system still doesn't pick up do this:
*Go to Accessories in the start menu, then Admin Tools>Computer management
*Next expand System Tools on the left and click Device Manager.
*Then right-click the top most device listed on the right and choose "scan for hardware changes".
Let us know
exactly whats is picked up then.
