The phone's previous owner flashed a custom ROM to speed the phone up a little bit more. if you can get back to the original owner and ask him to flash the original ROM, he should probably do it for you free of charge.
If he refuses or you can't get it touch with him, simply google for a tutorial on reverting the HTC One to it's stock ROM. You can ask around forums like XDA Developers for help, should you run into any trouble - people there are usually pretty friendly and always try to help.
If all else fails - bring the prone to a cellphone repair store and ask them to fix it. Watch out, though - they might charge you quite a bit.
