1. Click on Pearl (Start Button), in the search box type:
msconfig
and hit the enter key on the keyboard. It should open the System
Configuration Utility window.
2. Click on Services over the top and then at the bottom right corner, put
a check in the "Hide all Microsoft services" checkbox.
3. Click on "Disable All" button.
4. Click on "Startup" tab, and then click on "Disable All" button again.
5. Press OK button and then "Restart" button on the following window. Let
the computer restart.
6. Once you're back on the desktop, you'd get a window for System
Configuration Utility. Put a check in the box "Don't Show....." and then
press OK button.
7. Now, once again check the issue. If the issue is resolved, open System
Configuration Windows again and then enable all the services from Services
tab and then check the issue after restarting the computer in the same way
as mentioned above.
8. If issue is still resolved, enable half of the Startup items from Startup
tab and then check issue.
9. If issue occurs again, it means, there's a culprit in the checked startup
items. But if issue doesn't occur, then issue could be with rest of the
Startup items. Now, uncheck the first half startup items (that were check
before), and then check rest of the half items. Check the issue again.......
10. Now, if the issue occurs, then make a note of all the names of the
startup items and then follow the same procedure, for them. Now, you need to
be careful, as by design the System Configuration will sort all the enable
startup items to the top. So, it means all the entries would be mixed on
next reboot. From now on you need to make a note of all the entries that
you're enabling or disabling........
