Windows XP Restarts Unexpectedly

Windows XP Restarts Unexpectedly When Booting
1) During Startup

If you are encountering the automatically restart problem before you can logon to Windows, then you should follow the steps below in order to troubleshoot the problem:

1. Start your computer and keep tapping F8 to get the advanced Operating System Options.
2. In the Options, select “Disable Automatically Restart Windows“, Windows will start loading.
3. Now most probably you’ll get a Blue Screen of Death like the picture below:Windows_XP_BSOD

On this screen you will find useful information about what was the cause of this critical error that Windows has encountered. The most important information from the BSOD is the following:

* The faulting module or file name (SPCMDCON.SYS in picture)
* The name of the fault (PAGE_FAULT_IN_NONPAGED_AREA in picture)
* Stop Error Code (0×00000050 in picture)

If you get all this info, you can easily get what your problem is. Here is a list of most popular Stop error codes and their possible solutions.
2)Randomly After Logging In

If you can log in to your Windows system and the system restarts randomly, then do the following:

1. Right Click My Computer –> Properties –> Advanced –> Startup And Recovery –> Settings
2. Under System Failure, uncheck “Automatically Restart” as shown in the picture below:
