Hello , my english is not good, so ill try to explain as good as i can.
So 2 days ago i used my windows 7 with no problems, they worked perfectly. Yesterday i decided that i want to try windows 8, i downloaded them and installed, installation was good with no problems, but i didint liked them and deleted them. So i installed my olds windows 7, but there was a problem with extending fails, its stucks on 0% for like 10mins and after that installation goes normally, but it never been like that, it always was fine, never needed to wait, max 15mins for installing all windows. So okey i installed windows, caouse thought its normal and i kept installing my programs untill i wanted to install my game. I inserted my diablo 3 disc to my cd room, pressed on setup and etc, when it started installing it stucked on 0% and wont move... Expect not like with windows 7, after 10mins its continous, but with this game it wont even continou after 1hour.. And i dont understand what the problem it might be... Got newest updates, frame work 4. I thinking i might do somthing wrong with bios, but later on i made it to default and tried again, it was same. Tried everything, clearn install with deleting pertitions and creating them again. No clue what to do.
