Problems building first computer

[eurin]

This is my first go at putting a computer together.

I've got an Antec Sonata II, eVGA 7800 GT, the free motherboard deal (eVGA nforce 4 sli) in the box at the moment. I've got the processor, 1 dvd drive, ram, fans, and Harddrive currenlty hooked up. The computer won't boot, the pc speaker just beeps at me?

Any suggestions guys? The 18th power rail (-5V) is missing on the 24 pin power. From searching on the web, if I understand correctly, the -5V rail isn't used by newer motherboards. Do you think this is the problem?

I don't think the -5v is the problem

make sure none of the mother board risers (standoffs) are shorting the mother board

make sure that the 24pin power connector is fully seated
make sure the 12v 4pin power connector is fully seated
check to see if there is another 4pin power connector on the mother board (HD or floppy type - some mobos have them, others don't)
make sure that you have the external power feed hooked up to your video card.

check that cpu is seated properly.

remove the ram and only put one stick back in the board. move that stick to a different slot each time the motherboard doesn't boot.

remove anything that doesn't need to be plugged in right now.

I found a revision to the motherbook's booklet. They misprinted the banks and dims for the ram. So instead of having them in 1 and 2, they were in 3 and 4. (which the revision specifically says they won't boot in 3 and 4). Well, I'll give it another go when I get home from class today.

Thank you for the reply.

What beep code does it give you.
Depending on what make of bios you have then look up the correct code Here
That page show most of them.

Luck..........

Booted up just fine after switching the ram around. (I was originally checking for post with my roommates ram, since mine wasn't coming in until today.)

Everything runs great, 7187 3DMark05 on stock speeds.

Thanks guys.
