Why won't my Galaxy S3 sgh-t999 boot up?

AC Question

galaxy s3 sgh-t999 will not boot up, help!

ok so when i push the power button it will power on but will not go past the the blue circle the image that appers right after the Samsung logo then it will turn off.

i pressed the home+up+power key and it just turns off as well.
but when i press the home+down+power key then the up key it will stay on.

a thing to note the usb port will not work anymore.
but i have tried to wireless charge it and it will not do so for i have had it placed on the charing pad for many days.
yes i have tryed to charge a anther phone with it and it works well (it also is a GS3)

i think that the OS or the boot image may have been damaged or something like that.
so i need to keep all my stuff like contacts and apps (info) intact.

can anyone tell me whats wrong and what can i do to fix it?
