if the info i just called up is correct you should be running the video built in the intel 845GV chipset.
now it will fail to install if you have not loaded the main chipset driver first.
as you did not list your o/s i can only give you a link to intel.
download and install the INF EXE files first restart the system.
then install direct x update.
then go back to the intel link and download the GFX driver.

if all else fails you will need to load up a software program such as everest.
