no guides odd problem

ok blender was working cool for a while but then i got a new pc and all of a sudden using the menus is hard because the mouse moves to quick, and the first time i hit the b key i get no box guide lines for selection. also the camera has its outer box, but the inner guide lines are gone. i thought it was a display setting but still cant figure it out

trust me i understand have the same problem, its your graphics card you eather nead to up date or more likely dow grade your openGL drivers or buy a new graphics card or like me get fustrated and just ignor it.

good luck
