Is my PSU asploded or can i fix it?

My compy has been gimped and im typing this from my laptop. Please bear with me here.

In short, im having problems with supplying power but im not sure if the PSU is salvagable or if its even the PSU.



In long..
Whenever i hit the power button half the computer powers up...
The motherboard seems to be getting some power as evidenced by the "on-light" that one sees whenever power is fed to it, and the fan for the CPU and rear cooling fan are spinning and all the LEDs are on.
However, power to the graphics card and the two front cooling fans, are not being fed.
Also, a larger top fan is *twitching* but not spinning.

I recieve no input to my monitor so i cant see sh!t, BUT i dont hear the windows bootup sound if i keep the computer running. Barring any BIOS screens between powerup and reaching the desktop, I can guess that means the hard drives arent on or the motherboard hasnt much power

The powersupply im using is an
700W OCZ GameXStream Power Supply

The tower--
Antec900 Steel ATX Mid Tower Computer Case
NVidia 8800GTS
2.4GHz Conroe Core2Duo w/ Arctic Silver 5
4Gb G-Skill DDR2 800 RAM
320Gb SATA HDD
500Gb SATA HDD
ASUS P5N-E SLI mobo
Sound Blaster X-Fi XtremeGamer soundcard

using a Chimei 22-inch widescreen LCD monitor

Most of it put together in January of 2007 making it roughly 2 and a half years old


Any idea of where to start with this problem?

Seems like it's probably the PSU - it's probably not salvageable (I've never known them to be).

If the supply failed that badly that suddenly, it could easily have taken other stuff with it, too, and there's really no way of knowing if the components are salvageable short of putting in a another unit (save for things like HDDs that could be plugged into a working system).

It's probably worth buying a new PSU.  Worst case scenario: if the system is fried, you then at least have a new PSU to plug into a new one.

Good luck, hope it works out.

That happened to my old computer. I just unplugged the power cord until the little power light turned off, and then plugged it back in.
