How do I change what shows when I click on "new Tab" on IE?

[Gabby Little Angel]

I just had to reinstall Office, and a toolbar, and re-establish Yahoo as my home page, and now my new tabs that used to have frequently visited sites has changed. Where do I go to reset it?
@ guardrailjim: THANK YOU! I am just waiting for YA to let me have the option to choose a best answer so I can give it to you. Now I have everything back like it was before stuff began to disappear, and all is right (so to speak) in cyberworld again.

Top left of screen click - Tools - Internet Options - General - Tabs - Settings - When a new tab is opened, open:

If you want your blank screen back - choose "the new page tab"
Other attempts:
Try clicking "Restore defaults"
Experiment with the settings.
BEFORE doing anything, take a screen shot so you don't forget the settings you started with.

Screen shot instructions:
Press and hold "ALT" key and "Print Screen" key.
Your screen shot is now in memory.
Save it to a folder.
Click "Start" (lower left of screen).
Go to - All Programs - Accessoris - Paint.
Click the main screen of paint program.
Press "Control" and the letter "V" keys simultainously.
Save the screen shot to a file.
