Custom Build Power Problems?

[Sleepee]

I am in the process of making a new build system, currently i have plugged in:

Cooler Master GX 650w
i7 920 Processor
Zalman Heatsink and Fan

All this is connected to my Asus P6X58D-E motherboard,

I also have the other components: GTX 560 Gfx card, 8 gig (2x Matched 4gig Corsair Vengence DDR3 1600MHZ) Ram, 1TB HD etc etc.

Any way back on subject, I am trying to trouble shoot why my system isnt powering on, when the above 3 items are connected to the mobo and i press the power button all I get is a sound from the PSU then it powers off again. All the while it is plugged in the lights on the mobo are on, but I get no movement from any fans etc.

I have tried re-seating the PSU and checked all my power connections are secure. Any ideas what it may be?

Problem solved, had to breadboard and apparantly its shorting somewhere along the lines, apologies for not trying this before!

Apparantly it was one of the screws I used, slightly too big and ran over the allowed "radius" as it were so shorted the mobo! Such a stupid thing!! Taken me 5hours to figure it out lol
