"First, find out what company your computer belongs to.
Ex. Mines is a Dell computer
-------------------------------------------------------------------------------------------------------
Then i would go to Dell's homepage.
Ex. www.Dell.com
-------------------------------------------------------------------------------------------------------
Then i need to find the drivers download page.
Ex. For dell, it is in the support section.
-------------------------------------------------------------------------------------------------------
After i get to the driver download page, i put in the version of my computer.
Ex. Mines is Dimension 2400 (i know, my computer is kinda sucky)
-------------------------------------------------------------------------------------------------------
Then it'll bring me to the page to download the drivers for the computer. Scroll down until you see the video adapters-driver. There can be more than one vidoe adapter-driver, just pick the one you think is the best.
Ex. Mines have "Intel Intel Grantsdale G Integrated video," "Intel Springdale G Integrated video" and "Intel 845 G/GL Integrated video."
-------------------------------------------------------------------------------------------------------
Download one of the drivers and restart your computer. Run Maplestory and it should work fine.
I hope this helped :]"
