Why Is My Dell Starting Up With a Blue Screen and Option for Win 10 and Win 10 Pro

Summary

A "clean boot" starts Windows with a minimal set of drivers and startup programs, so that you can determine whether a background program is interfering with your game or program.  This is similar to starting Windows in Safe Mode, but provides you more control over which services and programs run at startup to help you isolate the cause of a problem.

How to perform a clean boot

These steps might look complicated at first glance, but following them in order, step-by-step, will help you get you back on track.

Use the following steps to perform a clean boot in Windows 10.  Perform a clean boot for Windows 7, Windows 8 and Windows 8.1

1. Sign in to the computer as an administrator.  If you don't have an administrator account, you can create one. Create a local user or administrator account in Windows 10 .

2. In the search box on the taskbar, type msconfig and select System Configuration from the results.

Install, uninstall, or run an application

After you restart the computer, you'll have a clean boot environment. Then, do one of the following, as appropriate for your situation:

If the installation or uninstallation still fails, that means this issue is not caused by application or service interference. You mght need to contact the program manufacturer for more specific support.

If the program runs correctly, this issue is caused by application or service interferences.  You can find out which application or service is causing the issue.   How to determine what is causing the issue by performing a clean boot

If the program still doesn't run as expected, this issue is not caused by application or service interference. You might need to contact the program manufacturer for more specific support.

How to determine what is causing the problem after you do a clean boot

If your problem does not occur while the computer is in a clean boot environment, then you can determine which startup application or service is causing the problem by systematically turning them on or off and restarting the computer.  While turning on a single service or startup item and rebooting each time will eventually find the problematic service or application, the most efficient way to do this is to test half of them at a time, thus eliminating half of the items as the potential cause with each reboot of the computer.  You can then repeat this process until you've isolated the problem.  Here's how:

1. Sign in to the computer by using an account that has administrator rights. If you don't have an administrator account, you can create one.Create a local user or administrator account in Windows 10

2. For Windows 10, in the search box on the taskbar, type msconfig.  (In Windows 8 or 8.1, swipe in from the right edge of the screen, and then select Search. Or, if you're using a mouse, point to the lower-right corner of the screen, and then select Search.  In the search box, type msconfig.)

3. Select msconfig or System Configuration from the search results.

4. Select Services, and then select Hide all Microsoft services.

5. Select each of the check boxes in the upper half of the Service list.

6. Select OK, and then select Restart.

7. After the computer restarts, determine whether the problem still occurs.

   • If the problem still occurs, one of the checked items is the problematic service.  Repeat steps 1 through 6, but in Step 5, clear the lower half of the boxes in the Service list that you selected in your last test.

   • If the problem doesn't occur, the checked items are not the cause of the problem. Repeat steps 1 through 6, but in Step 5, turn on the upper half of the boxes that you cleared in the Service list in the last test.

   • Repeat these steps until you've either isolated the problem to a single service, or until you've determined that none of the services are the cause of the problem.  If you experience the problem when only one service is selected in the Service list, go to step 10. If none of the services cause the problem, go to step 8.

8. Select Startup, and then select the upper half of the check boxes in the Startup Item list.

9. Select OK, and then select Restart.

   • If the problem still occurs, repeat step 8, but this time clear the lower half of the boxes in the Startup Item list that you selected in your last test.

   • If the problem does not occur, repeat step 8, and turn on the upper half of the boxes that you cleared in the Startup Item list in the last test.

   • If you still experience the problem after only one Startup Item is selected in the Startup Item list, this means that the selected Startup Item causes the problem, and you should go to step 10. If no Startup Item causes this problem, there might be a problem with a Microsoft service.  Repair the service, reset, or reinstall Windows

10. 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 Windows with the problem item disabled.  To do this, run the System Configuration utility and enable your Services and Startup Items, but clear the check box for the problem item.

1. Sign in to the computer by using an account that has administrator rights.

2. Select Start, type msconfig.exe in the Start Search box, and then press Enter to start the System Configuration utility.
   Note If you're prompted for an administrator password or for confirmation, type the password or provide confirmation.
   

3. Select the Services tab, and then select Hide all Microsoft services.

4. Select the upper half of the check boxes in the Service list.

5. Select OK, and then select Restart.

6. After the computer finishes restarting, determine whether the problem still occurs.

   • If the problem still occurs, repeat steps 1 through 5, but in Step 4, clear the lower half of the boxes in the Service list that you selected in your last test.

   • If the problem does not occur, the checked items are not the cause of the problem. Repeat steps 1 through 5, but in Step 4, turn on the upper half of the boxes that you cleared in the Service list in the last test.

   • If you still experience the problem after only one service is selected in the Service list, this means that the selected service causes the problem. Go to step 9. If no service causes this problem, go to step 7.

7. Select Startup, and then select the upper half of the check boxes in the Startup Item list.
   

8. Select OK, and then select Restart.

   • If the problem still occurs, repeat step 7, but this time clear the lower half of the boxes in the Startup Item list that you selected in your last test.

   • If the problem does not occur, repeat step 7, and select only the upper 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 you still experience the problem after only one Startup Item is selected in the Startup Item list, this means that the selected Startup Item causes the problem. Go to Step 10. If no Startup Item causes this problem, a Microsoft service probably causes the problem. To repair the service, Microsoft recommends that you reset or reinstall Windows.

9. 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 Windows with the problem item disabled.  (Run the System Configuration utility and enable your Services and Startup Items, but clear the check box for the problem item.)

Reset the computer to start normally after clean boot troubleshooting

After you finish troubleshooting, follow these steps to reset the computer to start normally.

1. In Windows 10, in the search box on the taskbar, type msconfig. (In Windows 8 or 8.1, swipe in from the right edge of the screen, and then select Search. Or, if you're using a mouse, point to the lower-right corner of the screen, and then select Search.  Type msconfig.)

2. Select msconfig or System Configuration from the search results.

3. On the General tab, select Normal Startup.

4. Select Services, clear the check box beside Hide all Microsoft services, and then select Enable all.

5. Select Startup, and then select Open Task Manager.

6. In Task Manager, enable all of your startup programs, and then select OK.

7. When you're prompted to restart the computer, select Restart.

1. Click Start, type msconfig.exe in the Start Search box, and then press Enter.
   Note If you're prompted for an administrator password or for confirmation, type the password or select Continue.

2. On the General tab, select Normal Startup, and then select OK.

3. When you're prompted to restart the computer, select Restart.
