New computer build will not start up [SOLVED]

[juicebox360]

Hello. I decided to build a new gaming computer. This was my first time building a computer, so I did not know much. Anyways, I finished building the computer and when I turned it on, all the case fans began spinning, the graphics card fan span, the DVD drive's LED came on and when I pressed the "eject" button, it opened. However, the monitor did not receive any signal and so it stayed black, and my USB devices did not light up/work. My motherboard is an ASUS P5QL Pro, so I couldn't hear any beeps during POST (that is, if it occurred at all). I went out to Radio Shack this afternoon and purchased a peizo buzzer. The thing is, I have no idea how to attach it to my motherboard!

I had a hard time installing the heatsink. I placed the CPU in the socket, and applied Arctic Silver 5 on it. I purchased a separate CPU cooler/heatsink rather than using the stock cooler, and when I opened it, it had a nice block of thermal compound on it. I cleaned the Arctic Silver 5 with bathroom tissue and I started to install the heatsink. I failed to acknowledge the "rule of diagonals", and I had to reseat the heatsink multiple times, ruining the thermal compound. In fact, while I am typing this, the heatsink is still loose.

There currently is no OS installed on the computer as of posting.

I have NOT YET tried reseating the RAM, clearing the CMOS, reseating the graphics card, or a "barebones" boot.

Here's the parts used in the build:
Case: Antec Nine Hundred

I cleaned the heatsink and tried it again, this time with one stick of RAM, and it worked! Thanks!
