how do i format sd card to my delve

I am really stumped, every time i try to put my sd card into my delve it just keeps turning on and off how do i format to my new phone i have a card reader and i was able to move my stuff to a folder on my pc but still cant figure it out! please help    

thankyou so much i now know how to do it, however yes my phone keeps shutting down when it asks to put in the card i can click the format tab and it starts to format for a split second and powers down ugh! so frustrating! so you think its a good possabilty my phone is whacked? lol i just got it last friday
                           thankyou again,one chicka

i have us cellular, i was able to get it to format after about 20 try's on my own and just when i was ready to give up it formated   i have no idea if or what i did differently. so i am still going to take it to the store and have evan the tech guy check it out. because with my luck, day 31 it will stop working lol . other than that i love the phone. the only thing i wish is that it had a spot to hold the stylus . but thanks again for your help. and i hope you had an enjoyable easter. 

do you have to format the card....and if i do will it erase my songs, i put a 2gb card in, then downloaded some songs, but i was checking my memory and just saw a screen saying format, wat does formatting it do

so u think i should just leave it alone, i mean i have 60 something songs and still have memory...i couldnt have that many without the card right

I have this same problem. I've tried to format my card, yet it still turns my phone on and off. ANY further help would be greatly appreciated.
