Hi, I just built my new computer, I put an ASUS P5K SE Motherboard in, new ram, a new power supply, an Nvidia 8600 GTS, and my old pentium core 2 duo processor. After I built the computer, I booted up and it seems like all the hardware works because the neons turn on, and all of the fans turn on. But when I boot up, nothing on the screen turns on, my friend suggested using the onboard monitor port, but my motherboard does not have one. I need your advice, I have already checked the ram to see if it is in the correct places. Also, I do not hear any sounds from the motherboard when it turns on.
