I finished up my win2k install and all the critical updates and such. I plugged in my external hdd (usb) opened up the admin tools -> computer management -> disk management. After formatting the external, i hit the x to close the computer management tool and immediately computer powers off and then reboots, like i had hit the reset button on the case. I didnt install any new drivers, well the original drivers for mobo and video card, but it is still a fresh install...a little over a day old.
