Q: BSOD BCCode: 7a

When I turn off my computer after it has run for awhile (10's of minutes to hours), the computer doesn't shut down, instead it attempts to shut down, generates a BSOD, then reboots.  I can then get it to shutdown after the reboot (provided I don't do anything else besides shut down).

The error message I get is:

Windows has recovered from an unexpected shutdown

Hi trumpet-mmb,

Thank you for taking the time to post on the Microsoft Answers Forums.

How long have you been having this issue?

Have there been any changes to your system recently that may have caused this issue?

Will you please run a clean boot on your system to see if that helps to clear up the freezing issue that you are experiencing?

Here are the steps on how to run a clean boot on your system:

First Step: Perform a Clean Boot

1.       Log on to your computer with an administrative account.

2.       Click Start.

3.       Type msconfig.exe in the Start Search box, and then press ENTER to start the System Configuration Utility.

4.       If you are prompted for an administrator password or for confirmation, type your password, or click Continue.

5.       In the General tab, click Selective Startup, and then click to uncheck the Load startup items check box.

6.       On the Services tab, click to select the Hide all Microsoft services check box, and then click Disable all.

*NOTE: Following this step lets Microsoft services continue to run. These services include Networking, Plug and Play, Event Logging, Error Reporting, and other services. If you disable these services, you may permanently delete all restore points. Do not do this if you want to use the System Restore utility together with existing restore points.

7.       Click OK, and then click Restart.

Second Step: Enable Half of the Services

1.       Start the System Configuration Utility. Refer to the steps above if you need to see how to do this.

2.       Click the Services tab, and then click to select the Hide all Microsoft services check box.

3.       Click to select half of the check boxes in the Service list.

4.       Click OK, and then click Restart.

Third Step: Determine whether the problem returns

If the problem still occurs, repeat the First Step and the Second Step. In the Second Step, click to clear half of the check boxes that you originally selected in the Service list.

If the problem does not occur, repeat the First Step and the Second Step. In the Second Step, select only half of the remaining check boxes that are cleared in the Service list. Repeat these steps until you have selected all the check boxes.

If only one service is selected in the Service list, and you still experience the problem, the selected service causes the problem. Go to the Sixth Step. If no service causes this problem, go to the Fourth Step.

Fourth Step: Enable Half of the Startup Items

Perform a clean boot by repeating step 1.

Click the Startup tab, and then click to select half of the check boxes in the Startup Item list.

Click OK, and then click Restart.

Fifth Step: Determine Whether the Problem Returns

If the problem still occurs, repeat the First Step and the Fourth Step. In the Fourth Step, click to clear half of the check boxes that you originally selected in the Startup Item list.

 

If the problem does not occur, repeat the First Step and the Fourth Step. In the Fourth Step, select only half of the remaining check boxes that are cleared in the Startup Item list. Repeat these steps until you have selected all the check boxes.

 

If only one startup item is selected in the Startup Item list, and you still experience the problem, the startup item that is selected in the list is the service that is causing the problem. Go to the Sixth Step.

If no startup item causes this problem, a Microsoft service most likely causes the problem. To determine which Microsoft service may be causing the problem, repeat the First Step and the Second Step without selecting the Hide all Microsoft services check box in either step.

Sixth Step: Resolve the Problem

After you determine the startup item or the service that causes the problem, contact the program manufacturer to determine whether the problem can be resolved. Or, run the System Configuration Utility, and then click to clear the check box for the problem item.

Seventh Step: Resolve the Problem

After you have finished troubleshooting, follow these steps to reset the computer to start as usual:

1.       Click Start

2.       Type msconfig.exe in the Start Search box, and then press ENTER.

3.       If you are prompted for an administrator password or for confirmation, type your password, or click Continue.

4.       On the General tab, click the Normal Startup option, and then click OK.

5.       When you are prompted to restart the computer, click Restart.
