Thanks for your answer and sorry i was unavailable for the last few days.
Anyways I tried updating the chipset drivers 2 ways :
-> first using the manufacturer's program (which is an old AMD installer); it installed old drivers (Version 126.96.36.199) and then black screen. After restarting both drivers say they didn't start properly. Firstly I deactivate the 7970M's drivers and reactive it, everything when fine there. Then I did the same for 7660G's and black screen again. (That goes on and on and on). having run this installer doesn't change anything to the legacy drivers.
-> secondly I used the legacy driver's optional program chipset update (Version 15.7.1), it had no effect.
For the bios update I read that it is a quite dangerous operation and thus would like to ask you a question beforehand; on the Manufacturer's site they say that it is only for Win8, should I go back to Win8 before updating or not ? ( cf. Support For GX60 1AC | Laptops - The best gaming laptop provider | MSI Global )
Moreover they wrote "SATA mode selection set to AHCI by default." What does it mean? Do I need to do something before the update ?
Waiting for your answer, TY

Did you do the above?
I disable the drivers Auto Update as well as Windows Defenders (the only Anti-virus installed atm) and then clean installed the legacy drivers again using DDU.
The "Remove AMD folder" option was checked thus doing as you advised.
Unfortunatly I didn't witness any sign of improvement after it.
After that I tried running Ccleaner's registery problem solver before aother clean install, didn't work either.
Any other ideas ?
