My laptop is about 8 months old. I was using it earlier today and a few of the keys on the keyboard stopped working, this has happened once before a couple of months ago but only for about 2/3 minutes. I restarted the laptop and the keys were still faulty then all of a sudden the laptop started displaying all the letters of the keys i had pressed in the search bar and then shut down suddenly. I then turned on the laptop again and where i type my password, letters were being typed really quicky then shut down again suddenly - this happened a couple more times then it started switching itself off seconds after turning it on. Now it wont even turn on - the light may come on sometimes but most of the time its just dead. My laptop is a Dell Inspiron 15R
