Z420 Fatal Error 928

HP Recommended
Z420 Workstation
Microsoft Windows 10 (64-bit)

I just purchased a refurbished z420 system, and whenever it goes into sleep mode I get the following error: 928- Fatal PCIe Error. PCIe Error detected slot 2 completion timeout.


I have researched it before and all replies has said to update the BIOS and chipset driver. The BIOS is up to date and I cannot find the chipset driver.


Is there anything else that I need to possibly investigate in regards to this?

reseat the video card and aux power connector to the card


remove all addin cards, boot and see if error is gone, then reinstall one by one


this error can be caused by a card that is not seated in the pci slot correctly, or  a bad aux pwr connection to the vid card
