Before starting everything! You should know, Windows Update (WU) gives BROKEN drivers for your AMD mobility card (probably for normals as well). So do not run WU unless you see security update.
There are different ways to break your system but no worries MS will do it for you 😛 lets skip that part and start with other stuff.
Step 1: Uninstall things
This is your very basic step to uninstall things from your PC, you can either use normal uninstaller provided by MS (Control Panel) or you can download solutions like Iobit Uninstaller. After uninstalling both Intel & AMD drivers from your system. Jump to Step 2;
Step 2: Uninstall things completely!
What you need?
– DDU (Display Driver Uninstaller): //www.wagnardmobile.com/DDU/ddudownload.htm
This product probably one of the best cleaner in the market, for GPU drivers. For past times when I was testing AMD's beta drivers, this little fella saved me dozens of times when things get bad 😛 I hope it'll also save you as well.
NOTE: You need Safe Boot
This is important to make DDU work at full power (and access level) you need to use that program in safe boot. If you don't know how to boot your PC in safe mode read following or skip it.
To safe boot your PC,
– Either open start menu and type MSConfig or use Windows + R and type MSConfig.
– Go boot tab and select Safe Boot (Minimal is recommended).
– Reboot your PC
Now you are ready for DDU, on drop you can select Intel and AMD but use clean and do not reboot option for first 😛 After cleaning those leftovers now you are ready for drivers.
Intel Drivers: //downloadcenter.intel.com/
AMD Drivers: //support.amd.com/en-us/download
Mobile AMD: //support.amd.com/en-us/download/mobile?os=Windows+8.1+-+64
First install Intel drivers, reboot then install AMD drivers. After installing Intel drivers that probably work but if its not don't worry install AMD drivers, the thing here, Windows may try to install basic drivers for your AMD Cards. Just ignore and install your AMD drivers. Do one final reboot you'll have fully working drivers 🙂
Before ending; Since I'm AMD user, I don't have Nvidia card, if you have similar problem you can try this solution for Nvidia card(s) as well. This is not an AMD exclusive solution. You just need to change AMD drivers with your Nvidia drivers. I suggest getting GPU drivers from Nvidia, AMD and Intel's sites not from your notebook's producer. I'm a Samsung NP350V5C-S09TR user, that's maybe exclusive 😛 to Samsung but I never get Windows 8.1 drivers and drivers supplied for Windows 8 (WiFi) gave BSoD on Windows 10 while all other drivers (none of others got from Samsung's site or its app called SWUpdate) I got working properly. Now I'm getting my drivers from producers of components.
