I just put into my computer a new motherboard (Asus A7V600), cpu (athalon 2400+), and new memory sticks (1gb corsair). I reinstalled windows xp without any problems. After the reinstall I rebooted as told to and when I go to "windows xp is loading" screen it takes me to the "you have incorrectly shut down your computer" screen where I can choose safe mode, normal mode, or the last working configuration. After I choose one (does the same for all) the computer gives me a beep and reboots and goes back to the same screen, "you have incorrectly shut down your comptuer." It keeps doing this, like an endless loop. Any suggestions?
