I recently put a computer togeather, and everytime I try to go online the computer reboots. I’ve reinstalled windows and reseated all of the cards several times, but it still happens. I’ve tried different modems and different slots on the MB, but it still happens. I can run diagnostics on the modem fine. As soon as I try to connect to my ISP the computer reboots. I would love it if someone could even point me in the right direction.
