Windows 10 on Dell Latitude laptop logs following warnings in Systems Logs every few seconds:
Log name: System
Event ID: 17
A corrected hardware error has occurred.
Component: PCI Express Root Port
Error Source: Advanced Error Reporting (PCI Express)
After a bit of trial and error in disabling various PCI-Express devices in Device Manager, I found that the issues was caused by Qualcomm QCA61x4A 802.11ac Wireless Adaptor. Reinstalling its drivers seem to have fixed the issue.
