Automated Restart of Windows 10 PC

Hello,

If Windows suddenly restarts without warning, or restarts when you try to shut it down, it might be caused by one of several issues. An outdated driver and software conflict are some of the possible reasons. Having said that, we suggest performing
the following steps:

Step 1: Disabling the automatic restart option to view error messages.

Many hardware driver or operating system errors will cause the computer to display a specific error message before stopping the operation or shutting down the computer. However, if the Automatically restart option
is enabled, an error message might not be displayed despite an error taking place. Disable this option to allow the computer to display the error message.
Follow these steps to disable the Automatically restart option:

• 
  In Windows, search for and open View advanced system settings.
  
• 
  Click Settings in the Startup and Recovery section.
  
• Remove the check mark next to Automatically restart under System Failure, then click OK.
• Restart the computer.

Step 2: Checking for failed hardware.

Hardware problems can cause the computer to restart unexpectedly.

Let us know if that worked out for you.

 

Random shut down and restart??

Computer: Intel (R) Pentium (R) Dual cpu
E220@2.406hz
2.42 GHZ, 2.00 GB of RAM
Windows xp

Ever since I replaced the fan (with heat sink) the computer has randomly shut down and then restarted, at first during streaming, and now, will shut down and restart anytime. I tried to replace the graphics card to no avail. *Confused *Mad

One suggestion was to replace the RAM.

Any suggestions on how to repair my computer?
