Win XP. Have Win 2K on it now. It was rebooting anytime I did any rendering
(CAD) or connect to the internet for video news. I held the power button in
until it powered down. Camera was working on this computer yesterday, no
trouble. I know the USB connections are correct been using them. After that
shutdown nothing comes up on the screen. Cannot access the bios at all. I
tried several times to clear the bios with the Jumper. (unpluged) no luck.
Power supply is a thermaltake butterfly 480W. HS is a thermaltake silent
boost. All power is on, all fans and even the light on the optical USB mouse
is lit. Don't see anything in my manual about an option on the USB voltage.
