Auto rebooting

[HankL]

Windows XP with SP2
I leave my computer running all the time. During the evening for whatever
reason it automatically reboots and when I go to it in the morning it is
waiting for me to enter my password.
THIS IS NOT WHAT I WANT IT TO DO. How can I stop it from doing this?
Thanks in advance for your assistance

If your computer is restarting spontaneously, you are presumably
blue-screening, and you are set to the default of rebooting whenever
that happens. It's a poor default setting and you should change it.
Right-click My Computer, and choose Properties. On the Advanced tab,
click Settings under Startup and Recovery. Under System failure,
uncheck the box "Automatically restart.

Now when the problem occurs again, instead of restarting, you will get
the blue screen with diagnostic information. Post back with those
details for more help.
