BB Bold :: 9900 Doesn't Switch On?

Getting really angry with this phone now, 2nd or 3rd day without it turning on, what happened was it was running out of battery and I plugged it in thinking it was charging, not realising i've not actually turnt the socket on (typical manic mum moment) come back to it and it wasn't wokring, so now I decided to leave it over night on charge, nope... so went and brought a new charger thinking it might be a charger issue. still to no avail. Now its randomly varying between red led flashing with long pauses, sometimes it would start loading with the blackberry screen and loading bar then restart itself back to black screen and red led instead on going on to the main screen, other times its coming up with empty battery and red line through it... i've tried installing the blackberry desktop software to get it working that way, removed battery etc, held down the end call button, all the usual suspect moves.. and still nothing. I really need this phone to be working i've all my numbers, sons photos etc on there, really dont want to do a whole system reset..
