My nokia c7-00 switched off many times and dont switch on again

.
press on/off switch of ur mobile
now remove ur battery and reinstall the battery without releasing the on/off switch.
repeat 3-4 times ....
it should work fine...then...

Try to restore and dont forget that the security code for Nokia is 12345, after restoring it, off the phone and on it again.

Remove ur sim, battery and mc... let it refresh and again put battery and sim alone... Press green button(call button) ,* and 3 simultaneously and switch on the mobile... make sure that while doing this the "Battery should be in charging"... later, format the memory card and use it... hope this works out well!! And maintain ur phone memory between 250-300 kb.... Al the best!!

The Problem with Nokia 3110c – Switching off and automatically restarting This is what happens. Nokia 3110 hangs, gets switched off and restarts randomly. More often, it restarts around 3 times or so and then gets switched off.
Possible Causes and Solutions Cause 1 – Phone Memory Full – Nokia 3110c mobile phone has got 9MB of internal memory.
Solution – Keep the free space between 350 to 500 KB, so as to keep things running smoothly on your phone and prevent Nokia 3110c from restarting.
Cause 2 – Changing Themes – Some people have reported that the phone restarts automatically when they try changing display themes on the phone.
Solution – Don’t get your phone loaded with too many themes downloaded from the internet or atleast, don’t switch themes frequently. These themes, mind you, also load up things into your already falling Nokia 3110c phone memory.
Cause 3 – Memory Cards – Some people have reported that Nokia 3110c restarts due to some issues with the memory card.
Solution – Remove the card, get it formatted and then insert it back and then restore factory settings. This just might solve the issue.
Cause 4 – Transferring data via Blueooth / USB data cable (or) Updating Music Library – A few people have reported that their Nokia 3110c mobile phone restarts when updating the music library.
Solution – Don’t try updating of music library frequently or don’t often transfer data in/out of your Nokia 3110c phone.
Cause 5 – MP3 files
Solution – This may seem dumb, but consider converting all your MP3 music files to WMA and then store them on the memory card. Some users suggested this.

To be frank, This mobile has this as a generic problem. As I told, The problem can come back again.

the switch button is or maybe broken
the best way is to send it right away to the nearest service center

Remove the battery & sim card.
After some time set it again.
Switch on your mobile it will again appear white dont worry.
Leave the phone for some time it will automaticly on.

Dont worry I have also faced the same problem.
Remove your battery & sim card after 10-15 minutes set them again.
Switch on your mobile it will again appear white.
Leave the phone, dont touch. After some times it will automaticly on.
