It seems that I've GL_ARB_vertex_buffer_object support but why it keeps crashing?

Just tested some on an Intel 945 here.

You need to use the -ARB versions of the entry points with this part; i.e. glGenBuffersARB and friends.

Worth noting also that the 945 is a software T&L part and will be emulating VBOs in software; not much point in using VBOs with this one really.

that's it thank you all,

Absolutely right, my aim is just to get familiar with buffer issue and to study the codes.
