I don't know if I'm asking the right question in my title because I'm so confused as to how to do a chipset update on my laptop. I downloaded the file (about 80Mb) from the Toshiba website and I think, to run the update, the ATI catalyst will be used on my computer but I do not know how to extract the file (file?) to start setup and I don't even know what extract means or does. According to the computer, it said that setup will start after extraction is complete. What is this whole procedure of updating the chipset driver about-can someone explain it with simplicity of how to do it to me. The reason I'm doing the update is because my usb hub it saying that it is an unknown device when there is no device connected to my laptop in device manager and there are multiple unknown devices listed when I connect my flash drive each time. The computer also says that software for the unknown devices has been successfully installed each time I connect my flash drive. When I start up the computer, for a fraction of a second I see a partial outline on the screen as if from a message box and I'm wondering if that has to do with the unknown device. My USB hubs (ports) are not working so I can't reinstall my printer software. I tried a bios update but it did not solve the problem. I don't think I have to boot the chipset update file from the CD drive like I did for the BIOS update do I? Where and how do I begin to update the chipset driver with my file (it is on my C drive) ? Thank You.
