Start thinking about what has changed since the time things worked ok
and
now with the restarting problem. Were there any changes in software
or
hardware? Any updates through windows update? If so could one of
those
been a driver update? What is the malware status of the computer?
How
do
you check it?
It could be the computer is restarting because of an error. Right
click
My
Computer | Properties | Advanced tab | Startup and Recovery - Settings
|
Under System failure untic Automatically restart. Ok out. Next time
it
restarts it might then go to a blue screen with an error message.
Record
that message verbatim. You can post back here with it. Also start
some
research on it using this site:
http://aumha.org/a/stop.htm, and
doing a
Google search on the error code can be helpful too.
For the auto login, it's not good security practice to set up a system
to
login automatically; All accounts should be set up with a strong
password
and no auto login, but if you want to, it's straightforward to do so.
Here
are several ways to do it.
1. Go to Start | Run and type in: control userpasswords2 | Ok.
2. On the Users tab, clear the Users Must Enter A User Name And
Password
To
Use This Computer check box and then click OK.
3. In the Automatically Log On dialog box that appears, type the user
name
and password for the account you want to be logged on each time you
start
your computer.
You can accomplish the same thing by:
Download and install tweakui for xp and use its auto logon feature.

Lastly you can add the Dialog box that comes up when running control
userpasswords 2 to the Control Panel with the following tweak:
Add Control User Passwords2 to the Control Panel (Line 1)
