Strange issue when upgrading the motherboard/CPU/RAM on one of our 2003\nservers. When I try to boot to the new hardware the system gets as far as the\nstartup splash screen but the system just sits at the scrolling bar and never\ngoes past it. What's really odd about it is that if I decrease the RAM size\nfrom 4GB (which is what the original motherboard had) to 2GB then the system\nboots and detects the new hardware. As soon as I bump it back up to 4GB it\njust sits there. What might the amount of RAM have to do with it?
