Motherboard failure?

Specs: Windows 7, intel
I built my desktop in 2008, the specs of it are:
8 GB ram
Nivida gtx 260
750w corsair power supply
eVGA nForce 750i SLI motherboard
3 hard drives
Intel core 2 duo processor 3 GHz
windows 7 ultimate 64bit

I was using it a few days ago when it froze, I sat for a few minutes then pressed alt+ctrl+del after that i got the blue screen of death, I let it do its memory dump but forgot to read what it said. It rebooted but I was bored so I just left the room, I came back the next day and it was still on I moved the mouse to turn on the screen and nothing happened, I pressed the restart button and still nothing showed up.

With my motherboard I always get the bios at the start doing the hardware check then it goes to windows. This time nothing was showing up on my monitors, and I know it wasn’t them because I have 2 video cards and 4 monitors and none were even registering I had a computer hooked up. I’ll save you some time and cut to the chase, I have done tests with taking out my RAM, video cards, hard drives, dvd drives, card reader, everything except one of the two video cards (and I tried both at separate times.) I am pretty convinced that my motherboard has fried and I just wanted to know if there was anything else I could try? If I need to get a new one I’ll go ahead and buy an i7 processor too.

Thanks

"I am pretty convinced that my motherboard has fried and I just wanted to know if there was anything else I could try?"

It would have helped if you'd have noted what was on the blue screen, that was the key to the cause. Have you considered that it may be the power supply?

"If I need to get a new one I’ll go ahead and buy an i7 processor too"

New board, new CPU, new RAM, at the very least.

I have thought that it might be the power supply but all my case fans run, dvd drives power on, the lights on my motherboard light up. i have noticed that the fan on my video card does not spin when i turn it on but i dont know if it only does that once your in windows or not.

"I have thought that it might be the power supply but all my case fans run, dvd drives power on, the lights on my motherboard light up"

A power supply has 3 main voltage rails - +3.3v, +5v, +12v. Any one of them may have failed. It doesn't take much power to spin a few fans & light up a few LEDs. Do you have another PSU laying around that you can try temporarily? Make sure you lighten the load - disconnect all drives, disconnect all external devices except for the keyboard & monitor, use only one stick of RAM & one video card. At this point, all you're trying to do is get the board to post & bring up a display.

so i am now in windows and i was going to check the event viewer to see what it said on the blue screen of death when my monitor went black, a few seconds later it came back on but then i got the blue screen again! but this time i read it and it was about my display drivers. But now i cant even see anything again >.<
