Computer randomly restarting?
Windoze has a default setting to restart when an error occurs.





**Windows XP


To specify what Windows does if the system stops unexpectedly


You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings might also prevent you from completing this procedure.





Open System in Control Panel.


On the Advanced tab, under Startup and Recovery, click Settings.


Under System Failure, uncheck "automatically reboot"





**Vista


1. Click on Start and then Control Panel.


Tip: In a hurry? Type system in the search box after clicking Start. Choose System from the list of results and then skip to Step 4.


2. Click on the System and Maintenance link.


Note: If you're viewing the Classic View of Control Panel, you won't see this link. Simply double-click on the System icon and proceed to Step 4.


3. Click on the System link.


4. In the task pane on the left, click the Advanced system settings link.


5. Locate the Startup and Recovery area and click on the Settings button.


6. In the Startup and Recovery window, locate and uncheck the check box next to Automatically restart.


7. Click OK in the Startup and Recovery window.


8. Click OK in the System Properties window.


9. You can now close the System window.


10. From now on, when a problem causes a BSOD or another major error that halts the system, the PC will not automatically reboot.
Reply:Try deleting everyting possible in your two TEMP folders.


Folder 1: C:\temp


Folder 2: C:\WINDOWS\Temp





If there is an error message that says you cannot delete the file because it may be in use at the minute, click okay and don't delete it.





Also, open up your computer (when it's off) and dust it out. Sometimes random restarting is due to the dirtyness of the inside of a pc.





Hopfully this helps....
