Thanks for the post and Welcome to HP Forums @jdnguy3n73,

I understand that your computer is not booting up. The power light comes on for few seconds and goes away. 

Not to worry, I will be glad to help. 

Have you tried a different wall outlet for the power cord?

Were any updates being installed before this issue started?
