Laptop keeps shutting down randomly.

Hi, I own a Dell Inspiron laptop. Recently it keeps on shutting down every time I try to run my laptop, randomly.. Some times it shuts down during the Windows loading screen, sometimes on startup, sometimes during logon screen..and so on I tried turning on without the battery connected to see if it was the issue of the battery but didn't help, then tried blowing air on the ariels to see if it was heating issue but didn't same didn't help .. I havent used any malicious software or opened up malicious sites lately I have updated my os which is win 7 to it's latest version, have got an antivirus, didn't show any virus lately. Any help would be appreciated very much..
 
You should be able to find your receipt on-line using the Dell account you set up when you bought the laptop...
