New system will not post.

okay. so i was going for a budget gaming pc and i had bought everything i needed:

AMD Athlon64X2 5000+ Black Edition
Thermaltake SopranoRS Case
Antec Earthwatts 430W PSU
Wintec AMPO 2x1gb ddr2 800
150gb Seagate Caviar HDD
Phillips DVD burner
XFX Geforce 8800 GS
GIGABYTE GA-MA78GM-S2H Mobo
CoolerMaster Hyper TX2

i put everything together and connected all the power cords and turned it on.
everything spun up correctly but the monitor would show nothing.
the little yellow light never turned green.
i'm using an old Dell CRT from the previous pc that we had.
the HDD worked, i could hear it spin up.
the DVD bay worked, i could open it up.
the cpu cooler, system fan, and video cards all worked because i could hear or see their fans.
but the system wouldn't post.
the thing is, this case didn't come with a case speaker and the old dell that we had used a series of lights on the I/O panel to indicate problems so i don't have any idea as to what the problem could be.
gigabyte said that i should RMA both the processor and the Mobo because i had no way to isolate which of the two it could be.
so i did.
and i waited two weeks for the new hardware to come in. after installing it yesterday, the same thing happened. the same exact thing.
i'm going to take it to the shop tomorrow and see if i just made a bonehead move while installing everything but i figured since they're closed today that i could post here and maybe find some sort of solution so i wouldn't have to worry about going to town.
please, if anybody has any sort of advice or solutions, do not hesitate to lay them on me.

update:
the motherboard has an onboard speaker apparently because if i put in the gfx card w/o the 6-pin cord plugged in, it gives me the long beep to tell me that the card isn't installed correctly.
i unplugged the dvd drive and the hdd and have tested both sticks in all 4 slots but still nothing as far as the display goes.
if i plug the 6-pin back in then i get no beeps which is supposed to mean that there is some kind of board, cpu, or psu problem, right?
is it possible for only one of the 12v rails to go bad?
because everything else gets powered up.
i will try to make sure that the cpu is lined up correctly but i really hope gigabyte didn't send me another board DOA...

Hiya, couple of things,
Take it all out of the case,
Chuck the motherboard on something non conducting, with just the psu cpu, one stick of ram, and video card, and see if you can get it to post.
It's odd you get no beeps at all normally - usually any error will give you a beep code.
I'm leaning towards mobo here but try the above and see if you can get it to post,
Good luck,
Jay

And try it with no ram installed and see if that beeps at ya.

One thing that can prevent post is an older bios that does not "know" your cpu type. This can cause the symtoms you describe. Do you have an older cpu that you can test with? If you do and the MB posts, flash your bios, put the new cpu back in and it will post. Keep in mind this is only One of many problems that can cause this. I am not sure of the 8800 gs is a PCI version 2 card or not but if it is that can cause no video in certain mb's. Good Luck

That's my guess too looks like you may be having a grounding problem. make sure that the stand offs in the case are in the proper location in regard to your mobo.
