Hi pi1ot,
Installing the chipset drivers should fix the problem but you have mentioned you already installed the correct chipset drivers. If all the drivers were installed in the correct order as prescribed in this link, please uninstall and then reinstall the chipset drivers only else, uninstall and then re-install all the drivers in the correct order mentioned in the link. If the issue persists, please add an screen shot of the Device Manager in your reply so that I can research further.
Do reply with results.
