Windows 7 无法检测显卡（可能是 d3dim700.dll 损坏）

这是一台配备独立 NVidia Quadro 1000M 显卡的 W520 笔记本电脑。显卡无法被检测到，NVidia 安装程序无法工作，因为它无法识别它，dxdiag 确实显示一个空名称，显示选项卡中的其他属性显示为 n/a。

我运行了 sfc /scannow 并发现了一个无法修复的（单个）d3dim700.dll 问题，以下是来自 C:\Windows\Logs\CBS\CBS.log 的部分日志：

关键部分是（我假设）.dll 与文件的预期哈希值不匹配。我以为重新安装 directx 可以解决这个问题，但微软安装程序说，我已经拥有最新版本，不会继续。

答案1

跑过Thinkvanage 系统更新。它已经多次帮我找到缺失的组件。

答案2

答案3

尝试使用 DirectX Web 安装程序运行时进行更新？ 关联

答案4
