Hi, Thank you for your reply. Given this situation, let us prepare clean boot to check if certain third party service causes conflict during startup. Clean Boot prevents software conflicts by preventing the startup items and non Microsoft services from loading. This way you can safely follow the process of elimination to check which application is causing this behavior. Refer: How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7 http://support.microsoft.com/kb/929135 Note: Ensure that you put your computer back to normal startup mode after completing the troubleshooting steps. Steps are available in the article given above.

No, it won't. As troubleshooting steps, it disables services that are enabled upon startup. If the issue disappear, that indicates certain service item disabled may be the root cause.
