Why does my computer shut off and reboot while w xp is loading? I see the motherboard logo, as usual, and then windows logo with loading dots underneath. I hear a click and the logo disappears. A white on black one-line message flashes on but it's too fast for me to read. Then, the computer reboots and the whole schmagaggie repeats itself. Will do this until I shut it down. F8 and delete don't help me because my computer knowledge level is low. Cannot get to safe mode. Was asked to choose last good session but when I chose it, computer did same thing again. Inside is clean; all 3 fans are clean and running; no skidmarks on mobo. This began the day I set up verizon dsl. Any ideas?
