1) Download the latest Catalyst 14.4 from HERE and save it on your desktop for example
2) Boot into Safe Mode (while the PC starts press F8 repeatedly and from the menu select Safe Mode)
3) Launch DDU
4) At INTEL select all the checkboxes on the right and press the second button "Clean and DO NOT restart"
5) At NVIDIA select all the checkboxes on the right and press the second button "Clean and DO NOT restart"
6) At AMD select all the checkboxes on the right and press the third button "Clean and Shutdown" (this one should take longer to finish)
7) Start your PC normally and don't worry if everything is bigger (gpu drivers are missing and generic are loaded by Windows)
8) Install the driver that you downloaded at step 1
9) Launch DDU again and click on "Set Windows Automatic Driver installation to default"
10) Restart your PC, everything should be back to normal now. Check if your games work
