System does not support OpenGL/framebuffer objects

Hi,
I'm running: Windows 2000 & Qt 4.2.3 Open Source.
When I try to execute some OpenGL examples included with Qt, I get the following error:
"System does not support OpenGL/framebuffer objects".
Reading the code, I figured out that my systems asserts both

Code:

---

!QGLFormat::hasOpenGL() || !QGLFramebufferObject::hasOpenGLFramebufferObjects()

---

. Both of them are false.
What can I do to correct this?
Also if I comment that, I get the picture which is somehow distorted (like skew) also some other drawings are displayed like "two". I don't know the name of that visual illness in English. You see two pictures of everything. I'll attach an image.

Please note that this happens only with code that has frame buffer.

What is the solution for that?

Do other (non-Qt) OpenGL based programs work correctly for you?

yes. i tried this code from NeHe lessons (the Visual C++ Code)
http://nehe.gamedev.net/data/lessons....asp?lesson=02

also, some other Qt OpenGL programs work fine (the code without any reference to frame buffer)

What video card do you have?

I'm not an expert on this but I think it doesn't have support for framebuffers. Please also try some advanced benchmarking tool like 3DMark. It will probably tell you your video driver doesn't support shaders, framebuffers and/or some other things. Are you sure QGLFormat::hasOpenGL() returns false for you?
