Marquee tool does not support rectangular selection

Hi everybody,
Some problem with my Photoshop. Everybody knows that if we want to select some area in the Photoshop file, we have to just choose the Rectangular Marquee Tool. That's OK. But when I choose Rectangular Marquee Tool and draw on some area, it just selects only square area. It does not support to select Rectangular area.
And When I choose Elliptical Marquee Tool, it just selects only round area, but not Ellipse area. And when I use Crop Tool, it is also facing the same problem. How can I set these tools working properly?
