Problem:

A)HDMI from Motherboard to Monitor

B)DisplayPort from Graphics Card to Monitor

C)HDMI from Graphics Card to Monitor

Reboots and reboots and doesn't stop until power is removed.

 

Background:
Took the PC on 2 plane trips totalling 17 hours of flight, a few bumps along the way. 1 Screw came loose off the power supply. Replaced Motherboard and CPU with new exact components. 

 

Troubleshooting steps taken:
Unplug everything in the PC and replug. 
Take out the motherboard and CPU and put everything together again. 
Added 3 more screws into standoffs (Originally only put 4 in due to laziness on first build).
Taken RAM out and tried to reboot.
Tried another monitor to no avail.
Turned off PC and removed power supply cable then held Start button for 60 seconds then tried to boot again.

Reset the CMOS (either the jumper or remove the battery for 10 seconds)

 

Unplug everything and keep it that way (eliminates dead components)

 

What you need to keep is;

-CPU

-1 stock of RAM

... so no GPU, no SSD or HDD, you even need to unplug the front panel stuff (button and I/O)

 

If that still will not boot, try again with everything OUT of the case (to eliminate a short from the case, it's rare but could happen)
