I entered into safe mode with networking only once. Saw that net wasn't working so I couldn't contact you here. After that I disabled the verifier settings and normally logged into windows after a restart (and the whole mumbo jumbo with the system restore which I mentioned before cuz I wasn't able to connect to the net even after I logged into "normal" windows OS).
Since now you are guessing that something might be wrong with the network card, I just want to point out that I'm a student, and live in a student dorm. They have high speed internet in the whole building and it's protected. By protected I mean we have to install a security programme on our computers with which we authenticate oureselves that we are students of that and that university (all students have their own user name and password). Well all in all it's kinda hard to explain, cuz I don't know how all this works in other countries or even USA. But anyway if there really is a problem with the network card, well since this is a laptop there isn't much to do besides to throw it away.
Thanks
P.S- This is getting more and more serious, nvidia drivers, directx, wincdemu, and now possible networking problems.... How the hell is anything working on my pc in the first place.
EDIT: The point is, maybe the security program has to do something with the networking/authentication/connection on my laptop. Just a thought.
