I tried everything but my iphone is still stuck on the apple screen

I tried all the pressing home button at the same time as power but nothing seems to work, either the screen goes blank or the apple sign is still there!
THIS HAS BEEN UP SINCE 12:40AM TODAY MIDNIGHT!
BTW I HAVE AN I-PHONE…

:DD Thanks A WHOLE LOOTT!

Step 1: hold power button and home button at same time until screen goes
Blank

Step 2: plug into computer(iTunes) you will see your phone so click on it and click restore and yes everything on your phone will be erased

Step 3: when phone is done restoring it
Will turn on and hopefully you had your ICloud on and if so you will be able to retrive your contacts
