GFX card related start-up problem? Help!

On Monday night I shut down my PC and went to bed - everything was fine during operation that evening yet when I wake up in the morning and attempt to boot it up, I get a series of beeps followed by nothing coming up on my monitor. The fans stay spinning/the power stays on, I can hear hard-drive chatter when the computer normally loads the windows logon screen. I can even type in my login password and hear the windows logon sound through my headphones but don't have anything on my display! So the computer is booting but there is something inbetween power on and windows actually loading thats failed overnight?

Given that the most glaring problem appears to be a display issue, I would assume logically that there is something wrong with my graphics card?

I don't know the beep pattern and I couldn't tell you exactly how many there are as they all seem to run together somewhat? It's definitely not one long continuous beep, more like a series of beeps that all make up one scary noise that lasts about 2-3 seconds during POST and doesn't repeat.

For the past month or so there has been the odd beep from the computer whilst in operation but as it didn't happen with any massive regularity or repeat itself for a period of time, I didn't think that much of it. I simply checked the cpu/gpu temperatures (which were both well within normal limits) and carried on.

So far I have tried the following;

- Reseating RAM & graphics card
- Trying to boot up using just one of my sticks of RAM
- Removed as much dust as possible from inside the case and checked connections (everything looks as normal?)
- Using a different plug socket
- Tried using a different monitor (tried my other DVI port also)

I am completely bamboozled now and I can only think a piece of hardware has fried but the problem is I can't identify with any certainty at all what it might be. My computer specs are as follows:

Intel Core2Duo e6600 @ 3.3ghz (voltages are at default)
EVGA nforce 680i SLi mobo
BFG Nvidia 8800GTX (comes overclocked as standard)
Raptor X 150GB Hard-Drive
Enermax 850w PSU
2GB Corsair Dominator PC6400 800mhz
Creative X-fi Fatal1ty Sound-Card

Any help would be greatly appreciated!

I would consider borrowing a friends card to test whether or not its the card. I would also try to makesure that you are using different cords when trying the other monitors. (just to make sure that its not simply a bad dvi cable...) I would check online to find a list of beep codes and what they mean in order to possibly narrow down the issue. Best of luck!
