Hello! I have an HP Pavillion dv6 6115ev laptop with AMD Radeon HD 6770M with an Intel HD 3000 switchable graphics and i am trying to make a clean format and install either windows 8 or 7. The problem is when i install the os and try to install various GPU drivers either form the HP support site or other sources the screen goes black and then when i try to boot it pops up the windows restore utility and it rolls back the systems so i can boot. Thats on win7. In win 8 it just freezes with a black screen and a repetitive sound. That happens only when i install AMD drivers, if i install the intel the laptop works fine. I have tried over 10 different driver versions even those from 2011 that the official hp site suggests. Is there any case that my GPU is failing? If so, is there anything i can try to check that?
