W700ds Blank screen

[gv260ea]

Hi, My W700ds won't post. Here is a description of whats happening during power on sequence. Optical drive lights up and makes noise the lights below the screen lights up and after a second only the Z light the battery light and the power light stays on. After that nothing happens. If i let it sit for a while the fans rpm starts to increase.
Here is what i have tried
Re-seat the ram
Remove CMOS battery
Remove HDDs
Press power button 10 times and hold it for 30 seconds while the battery and the adapter is unplugged
Plug in a display via the display port with an HDMI adapter.
No matter what i do the result is the same.
P.S. capslock numlock and scroll lock buttons does not work.

Here is how I fixed it. I had a p8400 cpu lying around I swapped it with the qx9300 and reset the Cmos. Then it started to work. I have put the qx9300 back in and it also worked. I think this is quite unusual.

Quad-core W700 boards will only post with a Q9*** chip installed.
