Windows 7 未偵測到顯示卡（可能是 d3dim700.dll 損壞）

這是一台筆記型電腦 W520，配備獨立的 NVidia Quadro 1000M 顯示卡。未偵測到顯示卡，NVidia 安裝程式將無法運作，因為它無法識別它，並且 dxdiag 從字面上顯示一個空名稱，並且在顯示選項卡中的其他屬性上不顯示。

我運行了 sfc /scannow，它發現了一個無法修復的（單一）d3dim700.dll 問題，以下是來自 C:\Windows\Logs\CBS\CBS.log 的日誌的一部分：

關鍵部分是（我假設）.dll 與文件的預期哈希不匹配。我想重新安裝 directx 可以解決這個問題，但微軟安裝程式說，我已經有了最新版本，不會繼續。

答案1

跑過Thinkvantage系統更新。它為我多次發現了丟失的組件。

答案2

可能的解決方案：

我希望我能幫忙。

答案3

嘗試使用 DirectX Web 安裝程式執行時間進行更新？ 關聯

答案4

先嘗試運行chkdsk /f，然後再試sfc /scannow一次。很奇怪，sfc無法替換文件。
