No boot, no beeps, green lights on, no display

HP Recommended
XW8600
Microsoft Windows 10 (64-bit)

My XW8600 Worksttion was working perfectly, switched off in the normal way.

 

Next morning pressed on button, green light on, no boot display, no warning beeps, fans running, but nothing on screen. Monitor on light normal goes from amber to blue, during boot sequence but remains amber

 

Checked PSU green light is on viewed through rear grille

Fans are working

Internal mother board green light is on

On button green light is on

HDD seems to start with one flash of HDD light

Tried another HDD

Tried another monitor

Removed graphics card, this tested OK in another PC

Tried another key board and mouse

Disconnected HDD, but still doesn't display Bios start up on screen 

Removed all other accessories and cables, so that just keyboard, mouse and dispaly cable are connected........still the same fault

Everthing looks clean and tidy, no burning smell

 

Doesn't seem to be starting bios correctly

 

Anyone got any ideas, what I should try next?

1. Experiment with a different power-supply.

 

2. Remove all the RAM, and start it up.

If the POST (Power On Self Test) starts, it should "beep" (or flash some LED, in a pattern) when it detects "zero" RAM.

If the POST does not start, or does not "complain", then suspect the motherboard.
