Re: no graphics need help!
Other than drivers and updates, if other cards work within the PCI slot I would say your onboard graphics card is shot.
I've had similar things happen with sound and video on motherboards, nothing changes and the next day they don't work. Updated drivers and software doesn't work, but when you try replacement cards they work just fine.
Sometimes they become defective just like any other piece of hardware. Just feel lucky that the entire MB didn't die. It may be time to upgrade the MB since you don't have any ethernet ports on the MB. You could either upgrade the MB or go WiFi by using a USB WiFi adapter (opposed to the PCI ones).
