No power-up only the little green light by the cpu lights up

I tried Parveens solution for this problem on 2 absolutely dead D845GVSR mother boards and it fixed the problem for me on both. On mine you had to permanantly short pins 92 & 93 of the LPC47M172 IC near the ddr ram slots.

There must be a reason for why the motherboard went dead in the first place because from the factory, pins 92 & 93 of this IC are not meant to be shorted. Albeit the motherboards work perfectly the shorting of pins on this IC get over the problem but the original fault is still really there but has been bypassed! Still having said that, what a result!

Power is dead

You cannot get a replacement board. The IC has to be replaced , possibly 3. These are U24 , U25 , U26. You would need specialist tools and ability to do it yourself.
