Can't Figure Out What's Wrong with My Computer

So a few weeks ago my power supply up and died; I would turn on my computer, it would turn on briefly and then shut down. I replaced the power supply and everything was working fine for a few days. Then while installing video drivers, after the computer turned off to restart, it wouldn't start up again. The computer would turn on, the fans would turn on and so would the video card and sound card, though nothing ever appeared on the monitor and the devices plugged in (the mouse and keyboard have small lights which normally turn on) wouldn't turn on either. So basically, the computer turns on in the sense that the core components are receiving power, there is just no picture on the monitor or any signs of the computer booting up.

Troubleshooting I have done so far: I tried my old video card which still works, I tried my old power supply which is significantly weaker than my new one and the problem still persists.

Any ideas as to what might me causing the problem would be much appreciated. Thanks

System Specs:

Intel Core i7-950 3.06Ghz
ASUS Sabertooth X58
6GB RAM G.Skill DDR3
EVGA Nvidia 260GTX 896MB
Creative SoundBlaster X-Fi Titanium
GS700 700W Corsair PSU
 
You may want to test another system with the working power supply to see if the new power supply you bought is faulty. I would even venture to try a different electrical outlet.

Another possibility is the motherboard is faulty, but I would test the new power supply first.
