Issue

Windows 10 on Dell Latitude laptop logs following warnings in Systems Logs every few seconds:

Log name: System
Source: WHEA-Logger
Event ID: 17
Description:
A corrected hardware error has occurred.
Component: PCI Express Root Port
Error Source: Advanced Error Reporting (PCI Express)

Resolution

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.
