From the video, it appears you are referring to the empty space in the action bar (blank space on the right). What are you using for your video; on board or separate graphics card? Reply back with info.

Additionally, you may check the following website for some suggestions;

Very minor. Are you running the latest Display driver given by optional Windows Updates or the Nvidia Support Downloads webpage for your card model?

Also make sure you followed best practices like these for a Clean Reinstall - Factory OEM Windows 7.
Drivers are handled differently in Windows 7 than in XP.

Make sure all of your Windows Updates are done, watch for repeat errors and utilize System Resources as shown in Troubleshooting Steps for Windows 7

Im using Geforce 550ti latest drivers- im using Hd from my graphic card to my monitior

Gregrocker. Im using the latest drivers from nividia

You should be working through those steps anyway if you're serious about getting to the problem.
