Hello, Recently I bought a new motherboard,processor, ram and a graphics card for my old system to upgrade it. The Processor is AMD Phenom X4 Motherboard>GIGABYTE MA78GM-US2H 2GB * 2 DDR2 Ram 1GB NVIDIA 9400GT However after upgrading when I installed xp it was ok.But after that I tried to install Windows 7 RC. But after booting from the DVD after welcome screen the process just stops. Only The blue wallpaper of Windows 7 shows. Previously I had 2 HDD as SATA and 2 Optical Drives.One is a CD drive and another is a DVD Drive..Before posting here some googling showed me having some problems with this mother board as sometimes it doesn't detect SATA HDDs or that kind of results.But nothing is clear to me..So please help me...Thank you in advance..
