I have just finished building my computer and it works perfectly fine. Today I tried to put in my 7800 GT but when I plug it in there is no picture on the monitor just black. Everything sounds the same just no picture at start up. I have a Gigabyte GA-VM900M Core 2 Duo E6420 Vantec ION2 460 Watt PSU 2 GB Ram 667 if that helps. (It worked perfectly until I put graphics card in)
Hi there.
I'm working on the assumption that the graphics card is a PCI Express card.
Remember that if you are swapping from on-board graphics to a card you have to go into the BIOS and tell the machine that the primary graphics adapter is AGP/PCI Express.
Plug the VGA cable into the on-board graphics port, start the computer and enter the BIOS, tell the computer to use the AGP/PCI card as primary, press F10, save the changes and exit the bios.
The computer will try and restart so let it boot to post and turn it off, then put in your card and try to boot again.
Please post back if you need more help or advice.
Good luck and thanks for choosing FixYa!!
With the card out go into the bios and set the bios to default settings, save the changes and exit the bios.
Then try the card again.

Did you plug a 4-pin power plug into the end of the card? (extra hard drive plug)
As the previous poster has suggested your Onboard Video Graphics card is set to load first. You will need to enter the BIOS and set the Primary Display to PEG1 (which stands for PCI-Express Graphics 1) That is the way it was on my GA-MA790GP-DS4H only i had to make sure to specify which PCI Express card to use as i have 2 of them.

I have tried it set on PEG and on PCI E but it still won't work.
