I dont have a system restore point, that was the first thing i tried.
I've installed windows 7 again and that's the point where everything went wrong. At first windows did not recognize my graphic card at all, dxdiag showed: standard VGA card. So i installed Catalyst for the drivers, now it says i've got the HD6520G it got a little better, but i just dont understand why HD6520G is showing instead of HD6720G2.
There is 1 thing i do know, my processor and graphic card are 1 together. (i dont know how to explain this exactly)
Processor: AMD A6-3400 APU with Radeon(tm) HD Graphics (4CPUs) 1.4GHz
