Question: Why does my computer using Windows XP, keep rebooting or shutdown everytime I turn it on?
The computer which is running Microsoft Windows XP Home/Pro keeps shutting back down in the early stages of windows trying to load. The computer could reboot it's self while trying to run a hard disk check (scan-disk scan), the welcome screen, after the desktop loads, or perhaps even when a certain action is taken on your computer.
The reason your computer may be rebooting like this, is usually caused because of one of two reasons.
1.) The computer Processor or Power Supply may be over heating. Too much heat can result in permanent hardware damage and boot failure.
2.) Windows is having a conflict or producing fatal errors behind the scenes without showing you any actual error information. These types of errors are known as the 'Windows Blue Screen of Death' more commonly.
In Windows XP, instead of showing you this 'Windows Blue Screen of Death' error on your screen like you might remember on earlier versions of Windows, Windows XP is setup by default to have the computer reboot instead of showing you this error. Why the change? I'm not sure, I can only guess Microsoft thought this new nick name was hurting their business. Who likes the word 'death' associated with a problem with their product?
Before making any changes in you're Computer or Software, we strongly urge and recommend that you back up all data to prevent any kind of data loss. We cannot be held responsible for any kinds of losses that may incur.
Problem #1 Dealing with Hardware Over Heating.
If you think or can confirm the problem might be heat related, you will want to make sure you do the following.
First, shut down your computer and load the bios screen. This is usually down by hitting a button like [F9] on your keyboard. If your unsure, just hit every [F] button on your keyboard as soon as you turn it on until your bios loads. Next, find the menu or location inside your bios that gives you a estimated temperature of your processor, system zone 1, and 2. Write down these statistics on paper. You will use this information to compare results after performing the clean out of your computer.
1.) Purchase 1-2 cans of compressed air, or obtain access to an Air Compressor.
If you see a major difference, turn the computer on and see if the error has resolved it's self. If it hasn't you may want to continue with troubleshooting [Problem #2] which is shown below.
Problem #2 Finding the exact error and problem with Windows XP.
In this exercise we will show you how you can make Windows XP display the error message that is associated with the constant rebooting and shutdown of your computer when it's turned on. First we want to tell Windows XP to stop rebooting when there is a 'Windows Blue Screen of Death' error. We want to see this error and not have it hidden from us by Windows XP forcefully shutting the computer down. To do this follow these instructions:
1.) Go to your Desktop and Right Click on [My Computer]. Left click on [Properties] at the bottom of this Menu.
(Startup and Recovery)
(System startup, system failure, and debugging information)
[Settings] <--Click this button.
4.) When the next menu loads, under the text (System failure) make sure [Automatically restart] has been [Un-checked or Disabled].
The above actions will now allow the error information to come through instead of your computer rebooting constantly when you turn it on, or when you do something specific that would trigger Windows XP to reboot the computer.
Once you have reached this point, there are so many things that could go wrong, or things that would cause you these kinds of errors. I would recommend looking for a listed file name. I.E. HAL.DLL, RT2500.SYS, or COMMAND.COM
Example: In my Windows XP blue screen of death, I noticed the error was caused by [IRQL_NOT_LESS_OR_EQUAL_TO]. The 'Windows XP Blue Screen of Death' displayed this as the main cause of the memory error in my computer system. I also noticed at the bottom that this may be caused or associated with the file RT2500.SYS.
Actions I would take to resolve this issue would be:
A.) Visit http://www.google.com and enter in "IRQL_NOT_LESS_OR_EQUAL_TO" into the search criteria field and hit 'Search'. After reviewing the results, I now understand there is a possible IRQ conflict caused by new hardware, or caused by some software I may have installed.
B.) Now I would do the same thing for the file name "RT2500.SYS". I now understand that this file is my Network Wireless Card driver, or associated with my Wireless Card Network driver in general. All of this was done by doing very minimal research that took me only about 2 minutes of my time.
Now that we understand what is going on, you can research what you should do to stop this. In my example, there may be a new driver I should be using from my Wireless network Card's manufacturer (LinkSys) instead of keeping the default driver Windows XP may have installed for me. I may have to move my Wireless Card to a different PCI slot on my motherboard. I may even have to remove the card from my system and buy another one to stop the error.
Once you can stop the error, you can stop the rebooting/blue screen of death/interruptions with Windows XP.
