I don't so much have a problem. It's more of a question. I need to know what graphics cards are compatible with an emachine w3107, or atleast what makes one compatible so i know what to look for.

Download Emachine w3107 Driver ..go to driverzone.com then download audio driver

Test all power and data leads that attach to your hard drive IDE,SATA

the leads from your (motherboard to your hard drive) make sure they have secure dust free connections and are not faulty or just replace them they might be faulty

if its a 40 pin flat ribbon type it will be the first to fail

make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty

even something as small as a faulty electrical fan and its lead can cause you problems

computers need all power and data to continue through every working device and to have an end so any faulty leads will end up with a computer error

make sure your graphics card is securely seated with no dust built up or in the socket

if you remove your graphics check the socket to make sure its dust free

restart your computer then reinstall it this should activate found new hardware wizard

hope this helps

Your system supports PCI Express x16. So look for a compatible video card which should atleast have 512mb of video memory.

Have you tried a different Graphics Card, looks to me like the onboard graphics card is at fault, there should be an AGP slot or PCI slot that you can plug a new Graphics card into then you should be fine...

goto www.emachines.com, go to support, enter your operating system, and select drivers and find your sound card drivers and download and re install them and re boot and you should have your sound.

You could tell us you model number or look it up yourself on the e-machine website(Link provided below).  I do know that the PCIe x1 slot is only about an inch long. Maybe that is why you didn't see it?
