When making questions like that you need to provide more details on your machine, eq: mobo type and chipset/cpu/gpu versions, and/or laptop or pc model.
1. Do you still have the dvd/cd that came with the laptop/mobo/cou/gpu/chipset, try that first.
2. when option 1 fails try https://www.amd.com/en/support download and run the auto detect tool.
3. If that fails, you can allways try snappy driver install tool from sourceforge, been using it for years now and has never failed me!
At least it keeps you away from that narly sites that offer you drivers but in the end creates more misery! and click-bait crap.
Snappy Driver Installer download | SourceForge.net RUN AS ADMIN!!!
If all that fails try make a new topic and state your mobo/chipset/cpu/gpu and pc/laptop type and if possible bios version, and ask anyone on the forum who still has the original install cd/dvd that came with the pc/laptop so they can make a copy for you, and send it or share it with you.
Hope it helps.
