Can Anyone give me a solution how to solve this?
From the comments...
Looks like you've got a jammed key on your keyboard, or a defective keyboard. If this is not a laptop, unplug your keyboard and see if the problem goes away. Otherwise, look closely at your keyboard for a jammed key.
response: yeah, its my keyboard broken. the DELETE key always pressed
