Custom Rig Won't even turn on

I attempted to build a computer for my friends girlfriend with a budget. I went on newegg where i got the parts to build that last 15 computers and this is the first time I've ever had this problem.

I connect everything and turn it on and nothing happens, no smell, no lights, nothing. I assumed something was broke so I rma'd everything and newegg sent us new parts. The same thing happens, nothing. I hooked up a different motherboard to the power supply and the power switch jumpers and it turned the computer on fine, all the fans spun, the hard drive powered up. Reconnected the gigabyte 945gz and nothing again.

Maybe someone could help? This is a problem that's been plagueing me for over a month.

here are the parts:
Intel Pentium D 805 Smithfield 2.66GHz LGA 775 Processor Model HH80551PE0672MN - OEM
GIGABYTE GA-8I945GZME-RH LGA 775 Intel 945GZ Micro ATX Intel Motherboard
EVGA 256-P2-N615-TX GeForce 7600GT 256MB GDDR3 PCI Express x16 Video Card
3DFuzion 1GB 240-Pin DDR2 SDRAM DDR2 533 (PC2 4200) Desktop Memory Model 3DFRMD1GB533D24
Western Digital Caviar SE WD1600JS 160GB 7200 RPM SATA 3.0Gb/s Hard Drive
NEC 18X DVD±R DVD Burner With 12X DVD-RAM Write Black E-IDE / ATAPI Model 7170A-0B
Linkworld LPJ12-400W (PSWB-400) ATX 400W Polished Chrome Power Supply

 

Hmmm. I'll start with this obvious thing....Were you certain that the front panel connectors were properly connected to the mobo? I once had an older case that confuse d me a bit and I had one of the power connectors in the wrong spot, making it unable to power up. Once I got it straightened out, all was good.

 

yes, I tried that, i tried actually putting it everywhere and every combination on the board. I think I might need someone w/ actual experience using this motherboard... ; /

 

Dead mobo? R.I.P! :cool

 

yeah but thats what I thought the first one was, I RMA'd the mobo and this is the new one newegg sent us... odds of getting 2 dead mobos?

 

Ohh...I see what your saying!

Have you done your compatability homework? (im sure you have)
ie...RAM etc.

That would be what i'd look at next!!!
Seems like you know about data cable connections etc.

Any error 'beep' codes on power up?
