What originally happened to cause this issue ?  Was the new PSU a stock replacement, and HP Z240 TOWER BASE MODEL WORKSTATION compliant.

@Tanegaterry,

An unplugged computer would have been safe from a power spike.  A plugged-in power cord does allow what is called "stand-by" power to the motherboard.  A surge can then fry the motherboard.  That green led is only 5v. Pull the power cord, and re-seat all ram.
