could I use the disks from my lap top?
Unfortunately no, unless the graphics driver is the identical driver. This graphics controller is no longer manufactured or supported.
One thing you might try is to be certain the correct monitor is installed.
To do this go to
Start > Control Panel > (switch to Classic View) Display > Settings > Advanced > Monitor Tab
The Monitor tab should say either "Plug and Play Monitor" in the "Monitor type" area or it should list the manufacturer and model number. If something else is shown, click the "Change..." or "Properties" button to select the correct monitor.

As far as the firewall...ok. But you still have no anti-virus program. ad-adware 2007 is not an anti-virus program it is a program to find and remove malware/spyware which are totally different things from viruses.
What all have you personally installed on the computer? Are you absolutely certain that this is the correct graphics controller? Did you check in Device Manager to be certain?
You might run a check on it with Belarc Advisor and see what it picks up. It is free and very easy to use. It will give you a good look at what all is on the computer
