Hold the on/off switch for 3 sec. (If that doesnt help remove battery.)

You could also use the soft-reset button which is inconveniently located under the back cover. Take the cover off and you will find the soft-reset button just above the USB connector.

Or (if the phone is still responsible) use a softreset tool like ShutXP.
Many Taskmanagers also have this feature.
