Windows 7 unexpected shutdowns

Hi guys, been using my Windows 7 rig for years flawlessly but i have started experiencing unexpected shutdowns recently when performing several tasks simultaneously such as instant messaging, streaming video on the web, playing music and a few tabs open in my browser.

each time the system shuts down it has been logged in the event viewer as shown in this screenshot:

Welcome to Windows Seven Forums.

Now that you've isolated the Event ID occurences, go back into Event Viewer as per your screenshot and click on the Details tab then select each event occurence in turn.

You should then be able to establish a common cause each time your computer shuts down.

If you can take screenshots of two or three of the detailed Event IDs and post them here we can take a look and with a bit of luck determine what is happening.

the event log online help suggests the following solutions:


Quote:
  1. Overclocking: Disable overclocking and see whether the issue happens when the system is run at the correct speed.
  2. 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.
  3. 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.
  4. Overheating: Check whether the system is overheating by examining the internal temperature of the hardware.
  5. Defaults: Use system defaults, and run the system.

the system is not overclocked & i have done memory diagnostic tests so i can rule those out,

is a 450w power supply sufficient for a pc with my specs and if it is a overheating problem will upgrading the power supply help?

Thanks for the screenshots as they establish that the system has rebooted without cleanly shutting down first.

Check this link for further information:

Windows Kernel event ID 41 error in Windows 7 or in Windows Server 2008 R2: “The system has rebooted without cleanly shutting down first”

The info posted by Hyperion 1 is particularly relevant as it helps to highlight the scenarios that can cause this event to occur and which you referred to.

i viewed the link and none of the scenarios match my problem . my system does not restart or display any blue screens/errors it simply switches off completely during use

In that case, it might be that you need to check these items from the article in question as a driver, memory or hardware problem such as a faulty power supply would shut the computer down:
  1. Overclocking: Disable overclocking and see whether the issue happens when the system is run at the correct speed.
  2. 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.
  3. 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.
  4. Overheating: Check whether the system is overheating by examining the internal temperature of the hardware.
  5. 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:
  1. Right-click My Computer, and then click Properties.
  2. Click Advanced system settings.
  3. Click the Advanced tab.
  4. In the Startup and Recovery section, click Settings.
  5. Click to clear the Automatically restart check box.
