Intel Motherboards : Fatal1ty x79

Hi was wondering if I could get some help I have an Fatal1ty x79 MB and over the week I wanted to upgrade the HDD so I remove my old one and put in the new one and since I have done that I'm getting no out put which is strange,

 

however on the MB according to the MB manual it has a thing called PSC (Post System Checker). the manual saying that if the lights are red then you have problem with a device such as CPU, Memory, VGA and storage, now on my MB it is saying I have an issue with the VGA, which is really bizarre. now I tried  removing the RAM and graphics card even tried a different graphics cards, and nothing I'm still getting no output, I've brought it to work and tried different graphics cards different slots etc and I'm still getting no out put, not even getting beeps or anything.

 

I'm a bit stumped really any help would be appreciated

 

thanks
