I am looking for the drivers for my HD4000. After trying some different drivers I came to the conclusions that I need the 15.7 drivers or older. Anything newer happens to make my system unusable. I couldn't find any download link under the tab for my graphics card on the main AMD driver support page. I am currently on the 15.7 WHQL drivers but these don't work either, probably because they are for different type of graphics cards. I currently cant use my laptop at all, so can someone please give me a download link to the 15.7 drivers (the version for HD4000) or anything older?
