My BLU Advanced 4.0 Will Not Turn On Properly.

I woke up one morning and I looked at my phone. Something was loose in it so I took off the back case to see the SD card was out. So I put it back in correctly (I think). I tried to turn it on but it directed me towards the Factory Reset page. I have tried factory reset but nothing happened. I have tried everything I can think of. PLEASE HELP!!
