Thanks.... I have flashed my motherboard,using the motherboard flash utility,because the afudos flash utility is not compatible with windows 7 x64 and until now everything is working as it should,i used windows loader 1.9 by daz to insert the certificate and the serial,and it activated without problems,i will format my pc and do a new windows installation,if i notice some problem i will report back.... I am using windows 7x64
