Hopefully there is an easy answer to this one. For some reason for the past five days, our secondary PC has decided to take it upon itself to restart @ 17:57 each day. It restarts fine - no error messages, etc as to why it restarted.
As far as I'm aware no changes have been made to the PC setup, and can't even find anything in Control Panel that would explain it.
PC is running on XP(home), SP3, with Avast AV.
I'm totally at a loss as to why this is suddenly happening.
