hi

do visit the Toshiba Downloads link



Select from there the exact model number of your laptop. As you can see from the screenshot, there is a lot of variations within the A205 laptop series. You may find the exact model number from the sticker/embossed text underneath your toshiba laptop. its the same place where you found the serial number.

Feel free to post here those information. i can try help you check the video drivers that you need.
