But I have some problems with the video drivers. In particular, at every start I get an error message about 'Load MMDriver Application'. First of all I have to say that my VGA are an AMD Radeon 7470M + the integrated Intel HD 3000 (my CPU is an Intel Core i5).

So I uninstalled all the video drivers (both the AMD and Intel VGA drivers) and reinstalled the new ones from HP Support site, but they are for Windows 8 (not for 8.1) and not updated; in fact I still get the error message, and I can see that the AMD Radeon 7470 is not working. Only the Intel HD 3000 works. In the Device Manager I get the Code 43 error on the Radeon. I've already updated the BIOS to the last versione, without success. Must I downgrade to Windows 8 or 7?
