new pc built, wont power up

i woner if anyone here can help. ive just assembled a pc from scratch but it wont power up. surely the PSU should at least power up when i switch it on buy no nothing happens. for testing purposes i tried pluggin the old PSU into the wall as well but that doesnt even power on. i wasnt aware that the PSU had to be connected to the pc hardware to work. any ideas?

also when installing the processor it said to apply thermal grease but i dont have any, is this a problem?

i assume it wouldnt have anything to do with the LED leads as the case i have which has the LED wired differs from the motherboard manual?

windows xp
DABSVAL, 550 PSU -

creative Inspire T7900 7.1 Speakers OEM
CRUCIAL 4GB 240dimm ddr2 SDRAM
SUMSUNG 320GB 7200RPM S300 8MB harddrive
GeForce 8800GTS 320MB PCIE XT
intel Core2Duo E6750 S775 2.66ghz4mb
gigabyte S775 Intel P35 Express ATX motherboard -

there's a cdin socket on the MB Which i could swear has something in it on my old asrock MB, should there somethin in there?
also, there's an 6 pin lead which comes out of the PSU but the only place i can see where it fits is the graphics card, is this correct?
