I am using MSI U115 11" netbook (OS: Windows XP Home, graphics card: Intel Graphics Media Accelerator 500) and today after I switched it on, desktop was bigger than screen.

To be exact: screen resolution was set to the lowest possible and I could move mouse outside of screen (but only below - left, right and up worked normally, mouse could not exceed screen boundaries). I changed resolution back to normal, but the problem with desktop being bigger than screen remained (as before, only lower part - cannot see task bar, etc. When I hit windows button on keyboard, only upper part of menu start is visible).

What I already tried was changing all kind of graphics and screen settings - none of them helped. I also tried to restore the system to few days before, but it didn't help neither.

What can I do to make the desktop look "normally"?

EDIT:

Some additional info regarding screen:

Sorry it's in polish - but let me explain. There are two screens I can choose (Monitor domyslny means default screen), but the second one (the default one) is not available. After I choose it and click apply number 1. is used (and as you can see it has only two resolutions available. There are more in the second one - but without 1024x600 though).

The two ticked and grayed out options here are Use this screen as the main one and Enlarge Windows desktop to match this monitor's size. Too bad I cannot change them. When I choose the second screen, the first box is unchecked and grayed out. The second box is available to be changed but it doesn't matter anyway as after applying changes it reverts to the first screen anyway.
