+Title: WHEA Event Viewer Warnings
+Description: A corrected hardware error has occurred...
+---
+
+I've been trying to debug any problem that makes my daily driver PC unstable. Previously, I debugged a [crash in KeePass](./keepass-crash.md) occurring whenever my machine went into power savings. It turned out the crash was from from an audio driver (this will be important later). 
+
+A couple days later, I started seeing the following error, one or two an hour.
+
+```
+A corrected hardware error has occurred.
+
+Component: PCI Express Root Port
+Error Source: Advanced Error Reporting (PCI Express)
+
+Primary Bus:Device:Function: 0x0:0x1:0x0
+Secondary Bus:Device:Function: 0x0:0x0:0x0
+Primary Device Name:PCI\VEN_8086&DEV_4C01&SUBSYS_86941043&REV_01
+Secondary Device Name:
+```
+
+But while debugging a DNS issue on my network (which was from a bad Domain Controller I had to decommission), I noticed the same error was now spamming my Event Logs - hundreds a minute, completely making my Event Viewer logs useless. So after fixing my DNS issue (It's always DNS) I started looking into this issue.
+
+At first Google search, this warning is just informative... which, is fine... doesn't help me though. So I looked a little deeper.
+
+Vendor `ven_8086` is apparently Intel, device `DEV_4C01` is just the Intel Chipset (so not helpful), and the sub-system `SUBSYS_86941043` is the USB controller. A USB controller having an issue, now that's interesting... 
+
+In an attempt to removal as many variables as I could with debugging KeePass crashing from an audio change, I disabled the `USB Audio` feature on my Asus motherboard... Could that be related?
+
+Yes, re-enabling USB audio removed this error from my Event Logs. It makes a bit of sense, I guess...
