I am running Windows XP on a Dell machine. For about a month now, I have had
a problem of it re-booting for no apparent reason. There is no pattern to
the re-booting. What causes this problem and how can I correct it?
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.
