Issue
Ever since I updated my motherboard's BIOS to version 3004, I have been getting repeated WHEA errors. These errors come multiple times an hour, sometimes even more than one per minute. I first noticed this problem throught HWinfo64's sensor window telling me it registered a "PCIe Bus Error".
Windows Event Viewer shows me that all the errors are coming from two system devices, listed in Device Manager as "Intel(R) PCI Express Root Port #5 - A294" and "Intel(R) PCI Express Root Port #7 - A296". The vast majority are coming from Port #5 - A294, while a much smaller number come from Port #7 - A296.
I should mention that Event Viewer reports all these events as "A corrected hardware error has occurred." so it's not causing any noticeable problems with using the PC, but I still find it concerning.
