The most common reason for this error is a damaged or loose PCIe device, such as a graphics card (GPU) or RAID controller. Other causes can include an outdated BIOS, wrong PCIe generation settings, or problems with power supply to the PCIe devices. In this article, we will discuss different ways to solve this error.
1. Update BIOS and Drivers
The first and most essential step is to ensure your BIOS and all relevant drivers are up to date. Keeping both the BIOS and drivers current can resolve numerous issues associated with hardware components. To learn how to update your BIOS, please refer to this guide. Updating drivers is equally important, as outdated drivers can lead to system incompatibility and errors.
2. Change the PCIe Slot Settings
Sometimes, modifying certain BIOS settings related to PCIe slot behavior can eliminate the error. These changes help by preventing the system from flagging non-critical PCIe card issues, which can be useful if the problem is due to a legacy or non-conforming card.
3. Remove and Reseat the Card
A common cause for PCIe errors is improper seating of the hardware component. For instance, if a PCIe card is not firmly or correctly inserted into its slot, the system may not recognize the connection, triggering an error. Reseating the card ensures strong electrical connections and correct alignment, often eliminating communication problems between the card and the motherboard.
4. Move the Card to a Different PCIe Slot
If reseating the card does not resolve the error, relocating the card to an alternate PCIe slot may help. Different slots support different speeds and lane configurations, so proper selection is important. Moving the card to a different slot can resolve issues related to a faulty or power-constrained slot.
5. Perform a System Extensive Test
This method is especially relevant for HP workstations, which come equipped with HP PC Hardware Diagnostics UEFI. Running a System Extensive Test can help to comprehensively diagnose hardware issues when Windows fails to start, or other solutions have not worked.
