Welcome to the forum.

I am not a HP employee.


Are you getting any audible "beep" error codes? If so, what is the cadence?


Your PC is about six years old. I would look at the PSU as the possible cause of this problem.


Check the PSU LED at the back of the chassis when the PC is connected to AC power. It should be solid green.
