Try to press and hold the power button and the home button (middle key) at the same time for about 10 seconds. 

If the phone still doesn't start, you could try to remove the SIM card and SD card and try to start the phone again. 

If the problem persist, try to repair the phone software using PC Companion:

In PC Companion, press start on Support Zone > Start on Update the phones software > Press the blue link that says "Repair phone". Do this without the phone connected to the PC and follow the on-screen instructions in the program.
