to find the right drivers for your video card, some information about the video card is necessary.
if you can give some details about the Manufacturer, model, version, chipset, amount of memory, for the card, maybe someone can help.
just saying "i got a video card" is as helpful as someone telling you "I got a TV, can you tell me how to fix it"
any information you can give is helpful.
Watch the screen as you turn the computer on.
Most cards display some info from the card bios as the computer starts. you have to be quick and may need to start several times to read it.
dont turn it on and off real quick as this can cause damage, leave at least 10 secs between switch ons
hope this helps
