Hello @mariocg,

Welcome to the HP Support Forums! It is a great place to find the help you need, both from other users, HP experts and other support personnel.

I read your post about the Graphic Drivers, and wanted to assist you!

You can try checking this site for Windows 10 drivers that will work with your product: 

HP Products - Where Do I Find Windows 10 Drivers and Software for My Model?

If you are having trouble installing the drivers, you can use the tool at the following site: 

Open the Windows Update troubleshooter

Keep in mind that Windows 10 is a technical preview, so it is possible that drivers may not be available for your product.  If you are still having trouble, try using the Go back to an earlier build option, in your System Settings: HP Notebook PCs - Upgrading to Windows 10

Once you are back to your original Operating System, check to see if you are experiencing the same issue. If not, then you may consider holding off on the Windows 10 upgrade for a few weeks, until drivers can be updated.
