System doesn't start at all, no beeps

Hello!

I decided to build myself a new desktop.
This is the first computer I am building myself.

I have the following parts:

Gigabyte P965 S3 motherboard
E6300 tray
Arctic Cooler Freezer 7
1 GB Geil DDR 667 3-4-4-8
ATX Miditower 400W
Asus 7600GT

The rest is not so important.

I placed the CPU in the socket, then I mounted the Arctic Cooler on top. I placed the RAM in the slot and the graphics card in the PCI-E. I connected the power supply 20 pin cable in the 24 pin connector and the 12V connector in the 4 pin connector. Then I started the power suppy and nothing happened. Not even the motherboard lights turned on.
I tried a different power supply with the same results.
Any ideas?

Chris
 
you sure you have the 20 pin PSU connector properly connected to the system board? Is the PSU set to 115v? is the start button connected to the mobo?
 
Check all of your connections again and make sure you put the start button correctly in the mobo. When you turn on your PSU, does that start up? If not then you have a PSU issue. I'm not familiar with that PSU so I can't help you from there, but I would get a better PSU.
 
Hi!

Everything seems to be connected well. There is on bottom right of the motherboard a PWR_Led and there are 3 pins vertically. But I have no connector for that.
The PSU makes a noise when I shut it off but the cooler of the PSU doesn't move at all.

Not all of the connectors/LEDS of my case are specified with +/-, so I connected these with the written part facing the SATA connectors.
Should I try connecting the LEDS with the written part facing to the back of the case, to the case wall?
 
I tried that, to no avail. The PSU fan is not spinning when I turn the PSU on. Does that mean that it is 100% that the PSU is the problem?
 
Most likely, since you need to get a good one to drive that system you got...couldn't hurt to get a new one...get a good 500W
