I cant intall my gpu driver (AMD) on my windows 7 Toshiba SATELLITE L850D-139, i tried everything, i searched for so many drivers and still cant figuer it out.

I tried the amd cataclyst and the crimson these 2 were recomended on amd site for the specific gpus but when i restart the laptop the fallowing error message "No AMD graphics driver is installed, or the AMD driver is not functioning properly. Please install the AMD driver appropriate for your AMD hardwear" and in the device manger where is already installed the AMD Radeon HD 7520G driver witch i guess is just for the integreted gpu has the error Code 43 in the Device status. I tried to reinstall them many times, hell even i tried to stop windows to update display adapter driver by himself with no success.




The specs of the laptop:

CPU: APU Dual-Core AMD A6-4400M
GPU: dual graphics AMD Radeon™ HD 7520G + 7610M (the 7520G is the integrated gpu, and the 7610M is the dedicated one, on the toshiba site they specifiy that the dual gpu is active).
HDD:Hitachi 500Gb.
RAM:4Gb
VRAM:1Gb

Try uninstalling your GPU driver with DDU(display driver uninstaller)... it'll wipe it completely.

DDU Download link

You should start your laptop in safe mode and uninstall it with DDU from there.
After that re-install the GPU driver.
