Why is my computer acting weird?

my machine is acting up.
I’ve attached a screen shot of the error message.
What’s the next step here?

Looks to be Wacom tablet related. Unplug if any usb drivers. Or you can try booting into Safe mode with the shift key down then disabling any third party devices.

That’s my first guess based on the partial screenshot.
