Desktops with the NVIDIA RTXA400, RTX5050, and RTX5060 graphics card installed experience an issue when booting to the Windows desktop. The diagnosis result shows a " PCI Bus: Fail " error message when opening SupportAssist and clicking " Scan Hardware " on the home page to run a quick scan.
This error is a false alarm. It appears when the PCIe connection is not fully detected, but it does not mean that there is a real problem with your graphics card.
Note: This is a False Alarm , you can ignore this message, and there is no functional impact to the system. To resolve this behavior, update Dell SupportAssist to version 4.10 from the Dell Support Site or click the " Update Now " button in Dell SupportAssist. Note: SupportAssist version 5.0 (expected in February 2026 (subject to change)) is needed to resolve this issue with the Dell Pro Precision 7 T1 PW7T1260. Back to Top
