Your laptop is equipped with switchable graphics. In order to update the AMD driver, the Intel graphics should be the current version. Go to this Intel link, and manually ( do not use the Intel Driver Update Utility) find the latest graphics driver for your laptop, as pictured. Download and save it to your desktop. If you don't know which version of Intel graphics you have, look in device manager.
Download these AMD drivers to your desktop.
For Windows 8.1 or Windows 7
Now delete the Intel drivers from your computer using 'uninstall a program' in the computer control panel.
Uninstall the AMD drivers from your computer using the 'uninstall a program' in the computer control panel.

Thank you for you help
I'm trying everything right now, i'll give you feedback as soon as i complete every step. Although i'l not be able to remove amd driver by "Uninstall a program" because i had to remove it by "Device Manager" otherwise my computer would crash. Is it gonna affect me ?
Also, i'd rule out Disk / Windows problems since i repaired everything, i have a fresh install, i repaired my Drive and i've corrected every registry error.
Edit: As soon as i uninstalled Intel driver and rebooted, my pc "regcognized" my HD 7400m. I went to "Device Manager" and it was there, but it had the yellow triangle warning (wasn't working). When i tried to install HD 3000 Driver, i got bluescreened again and it went on an endless BSOD loop until i had to insert my w8.1 dvd and restore.
So, in the end, this didn't work :/
