first you will get this bad poblem...Your computer restarts, and a critical error message is logged in the event log:
Log Name: System
Event ID: 41
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
The system randomly restarts and no Stop error BugcheckCode is listed, or the computer is completely unresponsive (hard hang)
To check whether this scenario is occurring, press the CAPS LOCK key on the keyboard. When you do this, if the CAPS LOCK light on the keyboard does not change when you press the CAPS LOCK key, the computer may be completely unresponsive (hard hang).
This scenario usually indicates a problem with the hardware. Another possibility is that a driver may cause this problem. To help isolate the problem, check the following items:
Overclocking: Disable overclocking and see whether the issue happens when the system is run at the correct speed.
Check the memory: Verify the memory by using a memory checker. Verify that each memory chip is the same speed and that it is configured correctly in the system.
Power Supply: Make sure that the power supply has enough wattage to appropriately handle the installed devices. If you added memory, installed a newer processor, installed additional drives, or added external devices, such devices may require
more energy than the current power supply can provide consistently.
Overheating: Check whether the system is overheating by examining the internal temperature of the hardware.
Defaults: Use system defaults, and run the system.
If you see that the computer generates a Stop error that contains a BugcheckCode value that is not reported in an event ID 41, modify the restart behavior for the computer. To do this, follow these steps:
Right-click My Computer, and then click Properties.
Click Advanced system settings.
Click the Advanced tab.
In the Startup and Recovery section, click Settings.
Click to clear the Automatically restart check box.
