I just built a new computer. AMD 2700 processor, 512MB 3200 ram, 120GB harddrive and a Biostar M7NCD motherboard. I loaded the OS (xp home), loaded the divers, did windows updates, loaded program software. The problem is that it won't shut down. After you attempt shutdown it will shutdown and then immediately reboots. I checked the power settings, looked for anything odd in he BIOS, and even tried changing the jumpers on the motherboard! I'm stumped, anyone have any ideas?
