Reformatarea se face la instalare Windows prin stergearea partitiilor (Drive Options) https://www.google.ro/......ps?/search
Instalarea driverelor se face imediat dupa terminarea instalarii Windows-ului si a Adobe Flash PLayer. Nu conteaza in ce ordine. Exista un program care-ti gaseste toate driverele: http://www.driverscloud.com/en
Apesi: Start the detections/Agent Installation/ Automatic Installation. Se downloadeaza un programel in folderul Downloads. Il instalezi si dai iarasi Start the Detection. Dupa ce-si termina treaba te uiti in My drivers si instalezi varianta cea mai noua. Succes!
