MSI GT70 MS-1762 (kit???)

Hi guys please bare with me here if I have posted this in the wrong section by all means move it!

Ok so I have a GT70 but cnnot find the exact model, it came with these specs!

Specs:
Intel® Core™ i7-3610QM Processor

Ok so Im having an issue getting this to work!

When I press the power button I get the white light on the power button and as far as I can tell is trying to boot (can hear the fans etc.) although there is no image on the screen!

I have changed the screen and no luck and have also tried an external which I did get to boot to what looked like the bios one time but the keyboard was unresponsive!

I have also tried a second graphics card in the machine and still nothing!

The other symptoms (if indeed they are symptoms maybe just observations that are normal?)

The touchpad lock light remains glowing orange? is that a faulty keyboard????? The keyboard does not light up like i would expect it to???

Also when I press the touch sensitive buttons at the top they dont seem to do the right thing ie. pressing one button makes another button flash? very weird goings on

Any help will be greatly appreciated guys

 

What happens if you remove the GPU and try and boot it?

 

Try testing with just a single stick of memory module one at a time and see what happens.
