The laptop is displaying a Cache Hierarchy Error after a week, specifically linked to event 19 WHEA ERROR in the viewer.
My computer (Acer Predator Helios 2019) is displaying event 19 in the Event Viewer. My specs are Intel i5 9300H, 32GB RAM, 2666MHz, HyperX GTX 1660 Ti mobile GPU. The laptop functions normally in games and idle, but this warning keeps appearing in the Event Viewer—sometimes three times per minute, occasionally every few seconds. The machine is operating correctly. Here’s the Event Viewer data:
- Log Name: System
- Source: Microsoft-Windows-WHEA-Logger
- Date: 20-03-2022 09:24:22 PM
- Event ID: 19
- Level: Warning
- Keywords: User: LOCAL SERVICE, Processor Core Error, Unknown Error Source
- Description: A corrected hardware error has occurred.
Additional details are available in the full event record.
You're experiencing the same problem with your HP Omen laptop, even though it shares the same CPU and GPU. It seems the recent Windows updates might have triggered the issue. The error logs show a fatal cache hierarchy problem once, followed by warnings in the Event Viewer afterward. Your friend reported a BIOS reset resolved it, but you mentioned your BIOS doesn't allow RAM tweaks. Have you considered resetting the BIOS or checking RAM settings?
