i have an asus p4p800se and am having the same problem as the person who posted "help dead computer". i was borrowing my friends digital camera and it was plugged into a front usb. i either unplugged it from the computer or turned it off or on, i dont remember. but the computer froze and would not respond to ctrl alt del. so manually shut down and when i attempted to restart i got nothing on my monitor, no beeps, no anything. ive tried a lot of things including taking out the battery as suggested in the "help dead computer" post and still no luck. did i kill my poor motherboard? any suggestions? thanks
