I have a compatible system but everytime i try to load windows vista..it boots to the cd,loads windows files,i see the microsoft logo and the a green/blue vista screen with no activity. My system is Asus M2N-SLI Deluxe with bios revision 0903, ATI Radeon X1950,Corsair CM2x1024-6400 DDR2(2 sticks 1GB),AMD Athlon FX-62 Dual core processor, soundblaster fx,650 watt BFG PSU. I have 2 Western Digital Raptor harddrives...one has Windows XP HOme Version 202 Service pack2 for an upgrade and the other is new for a full install.Windows has all updates,have all upgrade drivers. What could be causing this to happen???
