I am building a new computer with an A7N8X Deluxe motherboard, Athlon 2500+ Barton Chip. The problem that I am having is that I am using my old 80gig harddrive that I used with a MSI kt400 board. Well it goes to the menu screen asking for Windows xp or the other operating system but when I click Windows XP I get the blue screen of death saying the harddrive may not be configured correctly. Please help. Other components are Asus 7500 video card, and 2 256 ram running 266mhz in slots 1 and 3.
