Have you tried the hard reset, unplug power lead, remove battery with nothing plugged in hold the power button down for 30 seconds of longer.
Then try to turn back on with power lead if not replace battery try again.
For the benifit of others to help you more information i.e. your make modal no,, also when you say it goes to start do you mean into windows or just lights up then goes off.
Do not hold /press the button to hard down in-case it gets stuck which would make it shut down again (Stuck button).
