Let's run a Clean Boot to isolate what is causing this issue. Basically, a Clean Boot turns off all of the advanced features of the Operating System at the same time. We then reboot to see if the problem reoccurs.  We can then refine our search, turning the features back on one at a time until the problem reoccurs. Although the process may be time-consuming, this allows us to pinpoint exactly what is causing the problem.

Follow the steps outlined below to perform a Clean Boot:

Note: A Clean Boot is used for troubleshooting purposes. During the Clean Boot process, your System Display and Desktop will look and perform differently than in Normal Mode. This is only temporary. When the Clean Boot sequence has been completed, the system can be restored to Normal Mode by selecting the Normal startup option in the msconfig utility.

Please perform the following steps:

1. Click "Start", click "Run", type "msconfig" (without the quotation marks) in the Open box, and then click OK.

2. On the "General" tab, click "Selective Startup", and then clear all of the subsequent check boxes. You will not be able to clear the Use Original BOOT.INI check box.

3. Click "OK", and then click "Restart" to restart your computer.

4. After Windows starts, determine whether the symptoms are still present.

If the problem does not occur, please continue to use these steps to narrow down the cause of the issue:

1. Click "Start", click "Run", type "msconfig" (without the quotation marks) in the Open box, and then click "OK".

2. Starting with the first available check box (Process System.ini File), select each check box one at a time, and restart the computer as prompted until the problem is reproduced.

3. Once the problem reappears, click the tab that corresponds to the selected file. For example, if the problem reappears after selecting the Win.ini file, click the WIN.INI tab in System Configuration Utility.

Then, we can gradually narrow down the root cause by checking the items under the tab one by one.

Note: Microsoft strongly recommends that you do not use System Configuration Utility to modify the Boot.ini file on your computer without the direction of a Microsoft Support Professional. Doing so may render your computer unusable.
