First time trouble shooting a hardware failure

Heya all. My personal system which I built nearly 3 years ago died on me the other day. I was browsing the web on the machine when the screen went completely blank on me, and the hard drive began to make some very odd seeking noises. The noises continued for about 3 seconds and then stopped. The computer remained powered on however, but the screen was still blank/black. I cold booted the machine, but it came right back to a blank screen, I also did not receive any POST beep codes. I could hear the hard drives spinning up like normal though.

As of right now I have every piece of hardware unattached from the motherboard, and I still am not receiving any POST beep codes. Am I right in thinking that I should be getting some kind of beeps here with nothing plugged in? I've also tried pulling out parts piece by piece and trying to get some beeps, but I've got nothing. Sadly I do not have a similar second machine to diagnose my hardware with so it makes this more difficult.

This is my first time diagnosing a hardware issue where I am this in the dark. Can anyone give me some pointers as to the direction in which I should be going here? I have an Asus P4P800 motherboard. Does it sound like the motherboard is to blame here?
 
Dont take this the wrong way, but be sure your speaker is hooked up.
For a motherboard test, I would install the CPU only with no memory.
Should start beeping like mad at you when powered up.
If not then its either mother board or CPU
Good luck
 
The system/case speaker has worked like every since I built the machine. It use to give like a single beep every time I would turn the computer on. Now I get nothing at all.

So far, with the CPU hooked up or not I get no beeps at all.
 
if it is AGP, there must be a video card for there to be a POST.

If you have another good power supply, I'd swap that out, as the video dying and hard drive making weird sounds sounds like it could be your psu went south.
 
any light on the mobo? w/ cpu on the mobo powered on and no beep codes- essentially means ur mobo is dead or ur cpu is dead.
 
The light on the mobo does work. I will try booting it again with CPU and video card only and see what happens. I do have another PSU, I will give that a shot as well. Thanks you all for the input.
