First of all, new to the forums, so hello everyone I recently did a build of a new system for a friend's daughter. Her old computer was an outdated Compaq Presario- unfortunately, I don't have the hardware details. However, her new system consists of a Leadtek K8N motherboard, AMD Athlon 64 FX-51, 1 Gb Corsair RAM (matched pair), ATi Radeon x800 P.E. video card (AGP), and Creative SoundBlaster Audigy2 sound card. All of these parts came from my old system, and worked fine there. Because her hard drive was of low capacity, we opted to install a new, larger capacity SATA drive from Maxtor. Initial build was fine, but the system would not boot into Windows XP, and would hang at setup. Because of this, we purchased another version of Windows XP Home, and replaced the previous version with it. Boot up seemed normal. Installed all of the motherboard drivers (chipset, Sata, LAN), then used propietary Maxtor software to detect, format, and move all files from the original hard drive (IDE, btw) to the new Sata drive. After removing the IDE drive and selecting the Sata drive as the boot device in Bios, restarted the computer. Boot was slow, taking anywhere from 2 to 3.5 minutes to boot to XP. Hopefully, all of you builders out there will know more about this than I, and I thank you for your help in advance.
