HP Recommended
Product: HP Z440 Workstation

A month or so ago my HP Z440 wouldn't boot up, the problem was quickly solved by removing the storage HDD on my system. We later went to the bios to change the boot order and we also turned on secure boot. this resulted in the system outputting 6 beeps and showing no display.


Solutions we tried:
changing the GPU (we tested 3 different cards)
Removing CMOS battery
swapping CMOS battery 

Changing the PCIe slot the GPU was in

 

GPUs:
AMD Radeon RX 580

Nvidia GeForce 210
Nvidia quadro fx 1800

 

We got to a point where the system doesn't output 6 beeps but has no display and the fans are spinning, when a key is clicked on the keyboard, it starts beeping 6 times again.

I have seen the post made by SDH about the Boot Block Recovery but I am hesitant to try it.
All help is very appreciated, thanks!
