I am very new with this, so I will try to make it as clear as possible. After a clean instalation, no errors reported by the system, i enter my username and Password, and that´s all, nothing happends, is only this blank screen (well, Yellow/orange screen) and that´s all, there is only the arrowhead of the mouse and that´s all, it does not answer I have to turn off my pc in order to make it do something. and this is all over again every time I try it. Please help!!!!
