My Wacom Intuos Pen & Touch has stopped working
Open up the Device Manager by right-clicking "This PC/My Computer" and select "Manage". On the left pane, click "Device Manager". Depending of the version of Windows you're running, the tablet could be listed under "Portable Devices" or "Mice and other pointing devices".
Once you see it, move that window off to the side so you can still see the entry for your tablet. Now use the tablet as normal until it stops working. If it disappears from the list, you've probably got yourself a wiring/hardware problem. (My tablet's cable eventually developed a bad USB cable from years of moving around/use).
Since the tablet itself still recognizes you after it stops responding on the screen, wondering if you may have updated the software/drivers lately (even by accident by clicking an "OK" dialog by rote...) - try "rolling back" the driver to an earlier version.
If this is really new, any chance you could use Window's Restore function to go back a snapshot or two to when it did work fine? Always back up your important files (say, documents/designs etc) to another drive before doing anything. Good Luck!
