我正在使用Visual Studio Ultimate 2010和C ++。 我正在学习直接X编程，并试图运行示例文件。 我正在使用这本书＆＃34; 3D游戏编程简介与DirectX 11＆＃34;（Frank D.Luna）。
我正在尝试运行一个示例演示，测试Direct X是否适用于VC，以及我（学生）是否接受。程序没有运行它返回错误。
一个月前我进行了碎片整理，删除了所有内容并重启了我的电脑。 在此之前，当我最初尝试安装并运行并启动DirectX 11时，它运行正常。 现在，当我再次安装VS和Direct X 11时，我做的事与我之前做的一样，现在它不起作用。 基本错误是成功进行调试但没有运行，当我运行程序时，我得到一个空白窗口，错误无法创建DirectX设备。
我应该尝试重新安装所有Visual Studio版本 和直接X11，然后安装第一个视觉，然后直接X？ 如果我卸载所有Visual Studio，我的电脑会受损吗？ 我的显卡过时了吗？ 是因为我有旧版本的Windows 7吗？
