The ballcock is bad. Replace it.

ANS 2 - It's inexpensive and easy to replace with new style fill valve. Ballcocks are inefficient and prone to problems. Go to any 'big box' store and look at new Valves like Fluidmaster A 400, Pro 45, or similar - less than $20 and can be fitted in a half hour .

Usually the water filling up the flush valve in the tank. If it's bugging you, you can change the flush valve to a new one.
