2010 Alienware Aurora keeps shutting down

I purchased my Alienware Aurora back in Feb of 2010. Have had no issues with it until now. When it boots up it goes to the Windows 10 screen to input your password then shuts down. If I turn it back on it shuts down again within seconds. So I don't have enough time to do any diagnostics or even use a recovery disc. I'm thinking it's overheating and possibly the liquid cooling unit needs to be replaced. All the fans are running that I can see, so what are my options to get my baby back up and running?
