no display on my new p7h55-m build

[doit91]

I recently acquired a p7h55-m mobo from a friend which contains an i5 quad core. I set it all up to what I consider as done, it seems to start fine with all fans running and light on mobo comes on. all components are firmly in place, there is no signal on my screen and no beeping of any sort. I was reading that it could be due to my cpu not being compatible with the on-board graphics on the p7. I was wondering if simply installing a graphics card would fix this? I am fairly new to building computers and would appreciate a lame mans explanation or way around my dilemma
