Hello everyone, i need help with that "strange" problem. I installed Win 8 64bit with my old graphic card 9500gt inside, everything was perfect. Just after windows installed, i shut him down and changed graphic to 660gtx, i did it this way cause 660gtx is so big and to use it i must remove one SATA connection (dvd). With 9500gt windows works rly good but when i change to 660gtx i can't see single word, screen is blurry and windows 8 don't recognise my 660. Everything is fine on Win XP. I don't know what to do right now. Can it be problem with my motherboard with bios update max to Win 7 64bit, Win8 is not supported anymore by this board. If yes, there is any solution with NOT buying new board? Sorry for my english.
