Please read the following:
** Windows 7 and Windows 8.1 must be fully updated before attempting to install any AMD driver. All 'critical', 'recommended', and 'optional' (no language packs,etc) updates as well as any Service Packs (SP) must be installed before any attempt to install graphics drivers. If you do not get this message .... keep installing until you do:
The laptop Power Plan must be set on "High Performance"...not 'balanced'.
It might be a Windows related issue, I'll try to update my windows and reinstall my graphic drivers that way and see how's that working out and then I'll post again.
