That board has on board graphics. The on board switches off automatically if you install a video card.
First, check your monitor and cable on another PC. be sure they work.
Then try disconnecting everything from the system except Processor and fan, 1 stick of RAM, and power supply. Connect working monitor to the motherboard's VGA.
See if you get a BIOS screen.
Do a Clear CMOS / BIOS reset.

I thought it might have been two of the sticks of RAM or something so I pulled them out and nothing. feel the exact same no display I'm not sure if the speakers hooked up to the board. I'm not a son my other board there is just a green light and that's it. This one is green but the second I hit the power button a red one comes on as well. I have the video card plugged in, and the case fan CPU fan and the video card fan are all running.
hi to rule out a short to the case take the motherboard out and place it on a non conductive surface like the motherboard box it came in. then hook power supply, one stick of ram use motherboard manual to check what slot to use if just using 1 stick of ram cpu and heatsink and use the onboard graphics you should get a picture on the screen if not then you will have to determin whats the problem component. you can jump the two power pins on the motherboard to start it just make sure you only touch the pins for a couple seconds then take jumper off it should start.
Okay ruled out monitor and cable. Took out graphics card. Unplugged HDD. Unplugged disc drive. Left is PSU , motherboard , processor , case fan , CPU fan. Plugged into VGA of motherboard. Still nothing.
Does the motherboard support that particular Core 2 Quad ? if not, you`ll get nothing on the screen.
Did you run the compatibility tool from your link ?
Oh yeah, any cpu you put in a motherboard has to be compatible, especially when it comes to a 775 socket board.
You can`t just stick any spark plug in an engine
