Hey!
I have that HP DV7 6031eo laptop and it ran Win 7 Home Premium. But when Win 8 came out in here Finland I decided to upgrade my system. At first (maybe for a year) everything was perfectly fine, but now my computer is facing problems with that ATI Radeon 6650. Problems started after upgrading to 8.1 and updating those 6650´s drivers. Most of times my computer gets BSOD when I try to start my computer, and then error code is something like "atikmdag.sys". I have tried to unistall and reinstall those drivers (and beta versions) many times and from many different sources, but result is the same. When I even try install Catalyst software and other pieces to my computer, my computer gets BSOD again with error code "SYSTEM-THREAD-EXCEPTION-NOT HANDLED - (AtihdWB6.sys)". I have also reinstalled even Win 7 and Win 8 couple times - no result. But now somehow I got my computer to work at least that much I can write here. Now I see that my ATI RADEON 6650 isn´t showing in my computer anymore. It shows only some ATI RADEON 4200 Mobility, which is pretty unknown for me. I would appreciate if someone could tell how I get my computer to run properly with ATI RADEON 6650 without those lags.
Thanks already for reply, and sorry for my bad English skills. And if you need some more details - just ask.
