URGENT Nexus 5 not starting

[Bala C]

My Google Nexus 5 Experienced random shutdowns. (I found nexus 5 shutdown in the morning for no apparent reason. Battery was at 97% when i restarted)

Now, While i was copying my development game APK. I was copying the apk. Everything was perfect. While copying from windows 7, the opened the dialer app (and went to type *#*#4636#*#* to see Wifi state i was connected to)

While i was typing, my device Crashed. Black screen totally. I pressed the power button and it showed "Google" but is stuck on it for hours. It is not going any further, It shows "Google". When i press the power button again, the device stops and again shows "Google". So i pressed the Power button for a fairly long time and now the device is shutdown. (Totally shutdown). I tried restarting but to no avail.

Please help start my Nexus 5. It's running Android 4.4.2/
