Worcester 24i Junior - Wont Resest?

Boiler kept turning off probably due to cold weather conditions, pressed reset and it fired back up first couple of times. then today it completely went....tried to reset a few times and made some strange noises but wouldnt fire back up. Have tried again a few times and now the reset button doesnt even seem to work (all the lights used to come on when i pressed it and the boiler would try and restart). Has my reset button gone as well as my boiler???
Can anyone please help!!
