Laptop crashes while playing LoL

[Chooty]

Hi ,
my recently purchased Dell Inspiron 15- 5558 , completely crashes and wont respond and also makes this annoying zzzzzz sound after crashing while playing LoL after only a few minutes and i have to force shutdown by holding down power key , nothing else works .

it happened again but this time gave me a blue screen said it's a NMI hardware failure and restarted.

If this is a new computer you just bought, you should be contacting the place of purchase or the manufacturer. New computers should not give you any problems like this.
