Though Norton reports no virus ( assuming you got the latest virus definitions for it) , there might be sasser worm

The PC that is rebooting is not necessarily infected with a virus.  However it needs MS04-24 (I think), its the blaster patch.  Somewhere on your netowork a PC is scanning and attempting to infect these rebooting machines.  The machines that are rebooting may never actually get infected(which is why anti-virus says nothing is wrong), but until you close the back door with the MS patch, they will continue to reboot.

The virus blows up the LSASS service in an attempt to infect, which causes the reboot.
