Edit: The YouTube link is not working. Do you maybe have the settings for this video on Private?
If so set it to "Public" or "Unlisted"

For the Clean Boot, because this is important.

(Step by step guide)

• Press the Windows key and "R" at the same time.
• Copy and paste "msconfig" (without quotes) into the new window and press ENTER.
• Click on the "Services" Tab. (Arrow 1)
• Select the field "Hide all Microsoft services" (Arrow 2)
• Click on "Disable All" (Arrow 3)
• Click on "Apply"
  
  
• Now click on the "Startup" Tab. (Arrow 1, next image)
• Then click on "Open Task Manager" (Arrow 2)
  
  
• Click on the "Startup" Tab in the Task Manager. (Arrow 1, next image)
• Click on "Status" (Arrow 2) (The start up applications are now sorted by status (Activated/Deactivated)
  
• Select the first entry in the main Window and click "Disable"
• Repeat this for all entries.
• Click "OK"
  
  
• Restart your Computer.
• Start TS3 from the "TS3W.exe"

If the problem is gone in clean boot mode, please don't reverse the process without informing @puzzlezaddict or me.

To reverse the process just do everything in reversed order, just choose "Activate" in the Task Manager, and "Enable" in the System Configuration App.

And don't forget to restart the PC at the end.
