I have tried to install Windows 7 Ultimate on my PC several times...It will not install... get blue screen with bird on it and rotating icon...forever! Do I need to update the Bios/drivers or will this MB(ECS GEFORCE6100SM-M V1.0) with Athlon 64 X2 Dual Core (4800+) and Phoenix Award Bios V6.00PG run Win 7 Ultimate without updates?
