installed new motherboard but system is not picking up motherboard

What exactly is happening? Does the BIOS POST? Is the hard drive detected in the BIOS?

On a new motherboard you have to reinstall XP.

Hi i'm not too knowledgeable tested everthing else on my pc was working ok so motherboard was my last shot.
xp formatted on old pc
I dont hear hard drive working
system starts fans going
ok i do have stupid question in another area
this new motherboard which is gigabyte ga-7n400 doesnt have monitor connection
i'm thinking do i need video card

Yes you need a Graphics Card:

ga-7n400

http://www.giga-byte.com/Products/Mo...ProductID=1672

1 x AGP slot (8x/4x-AGP 3.0 compliant), supports 1.5v display card only

ok that's good i'll just buy cheap video card
still need to know y my hard drive isnt making sounds

I would recheck the connections if you think that it is not working.

You really don't want your hard drive making sounds.

As long as it is spinning. A good new hard drive should be pretty silent.

When you get a graphics card you will be able to see if the drive is detected by the BIOS.

And again you will need to re-install XP onto this motherboard.

thanks make sense to me . i know i can't seee whats happening but u can always hear hard drive if u listen doing whatever it does.

Installed gigabyte ga - 7n400 motherboard put in video card nothing comes up on monitor when i power up

What is the make and model of the card?

Are you sure that it is compatible with the motherboard?

When you say nothing comes up? Not even a No Signal message?

Does the monitor LED go to green?

What exactly is happening?

expert colour dsv3365e video card, just put this in to test pc before deciding on something better. tested video card on other pc no problems. I do have no connection coming up. power up fans start up nothing happening.
