go to the HP site for the z440 download the service manual.............READ doing so will allow you to use the HP troubleshooting steps hp wrote 

 

the symptoms you describe sound like a power short or possibly a bad motherboard, remove all cards ram except for vid card and just one ram stick (in proper slot)
