Unhappy [Q] Impossible to restart my Moto G after installing Cyanogenmod 11

Hi everybody,
Today I tried to install cyanogenmod several times on my moto g but each time it was still stuck on the cyanogen logo until I decided to leave it on for hours hoping it turns . when my battery is completely discharged, I tried to relight it charges but nothing happens, it stays on a black screen and occasionally when I connect it to the PC detects the LED lights and smartphone displays me that the battery is at 0% and then it goes off again, then stops responding and back on the black screen. No button responds so I do not have access to recovery mode or anything else. The moto G is Rooted, the bootloader is unlocked and I did a full backup before installing.
Can you help me please ( sorry for sorry for spelling errors i'm french)
