Lol, i wish it was just simple like that.. I guess there can't be much help cming out of this...I am sure, that I got a virus and AVG made it worse by deleting some files and drivers, so I will format my pc in few days.. However, right now it fits me cause I got exams in 3 weeks and need to get prepared.. If those issues continue after I format my pc, then something is definitely wrong.
