Mouse off center.

On my dad's PC his cursor goes "off center" when launching certain (all?) games.
He has to move the cursor down and to the right of the place he wants to click. And that means lots of things become unreachable.
The problem seems to disappear when going from full screen into window mode.

This is normally ok. But he wants to play Battlefield 3 Beta, and it already runs slow as it is without windowed mode.
Does someone happen to have experience with this? I tried changing resolutions of the desktop and the game, which doesn't help.
I might try a new mouse, cause he is using a wireless one now which was cheap. Could that be the issue?

If you know a possible solution, it would make him very happy :)

Oh he is using Windows 7 64 bits
6870 or 6850 I think. Updated those drivers to a couple versions but it doesn't help either.

He isn't using anything like DPI scaling or enlarging default texts in Windows is he?

It happens in more than just that game. How far away is he sitting? TV length? My suggestion is to just lower the resolution so things seem bigger.
