Hello,I am Japanese. 
I'm sorry if you can not decipher English.
Although I started with Windows8
I'm getting errors If you are returning to Windows7.
It is a spec of me now.
win7
core i7 3770
GTX680 OC
16G DDR3
An error indication is custom command.dll etc
2005 C++ As well After you update
Screen is attached, but it is still pitch black.
It is not taking the time to excuse, but thank you.
