    I would  say the system is getting a Blue screen error message.

    First Lets Disable Restart on system failure.

    First we want to check if you are getting blue screens.

    To make sure what we want to do is stop windows from automatically restarting and display the blue screen error message.

    Right click MY COMPUTER, choose PROPERTIES, choose ADVANCED, choose the SETTINGS button in the Startup And RECOVERY section, and uncheck AUTOMATICALLY RESTART.  Click APPLY and OK.

    We want to run the offline crash diagnostics to get a quick snapshot at what could possibly be the problem with you getting Blue screen error messages.
    First we want to download the offline crash diagnostic. You can obtain that
    Now we want to Run the Offline Crash Diagnostic tool
    After you save the WindowsXP-KB923800-ENU.exe file, follow these steps:
    1. Double-click the WindowsXP-KB923800-ENU.exe file to install the Offline Crash Diagnostic tool.
    The installer adds the Offline Crash Diagnostic tool files to the %Windir%\Pchealth\Helpctr\Binaries folder.
    2. Click Start, click Run, type ocadiagnostic.exe,and then click OK to run the Offline Crash Diagnostic tool.
    3. Agree to let the tool send information to Microsoft. Then, click Next.
    The tool performs the following tasks:
    " The tool determines the number of dump files on the computer.
    " The tool finds any dump files that are located in the %Windir%\Minidump folder. You can choose to send all the dump files, or you can choose to send individual dump files.
    Note The last 10 dump files to be created are collected. Dump files are not collected if they are more than one year old.
    " The tool automatically sends the dump files to the Office Crash Diagnostic Microsoft database Web site for analysis.
    " The tool downloads the response URLs.
    " The tool displays the response IDs. The tool also provides hyperlinks to the Office Crash Diagnostic Web site.
    Go ahead and report back the Responce IDS with your next post.

    Have you verified that there are no bad caps on the mainboard, or video card?

    also, while we are in HW diagnostic mode.......

    I would even double check the HDD with the Manufacturer's util on the UBCD as well....

    rebooting can be due to almost anything; i would check :
    -the cpu temperature - you can look at the temperature,after a crash, in the bios, or install speedfan :      
    -the power supply -  swap in another one, or calculate what you need  :      
    -bad caps; inspect the mobo for them; info :

    nobus has a good idea.  Check with the user to see if they are doing the same operations when it reboots or hangs.  They may be doing somthing that is strainious on the video card or cpu.  In most cases, over heating will cause the system to go into a dump and blue screen.  This is just one of many things to pin point the issue.  Did you change the paging file size?

    I agree with firekool's comment. Even I would set the system up for a memory dump and then analyze it to find out what's causing the issue.
    also look at on how to analyze the dump
