Over the last few days, and especially today I've been getting a lot of crashes. Sometimes audio/DX11 errors, sometimes the game just closes.

Event viewer says WHEA-Logger Event ID 19. A corrected hardware error has occurred.

Reported by component: Processor Core
Error Source: Corrected Machine Check
Error Type: Internal parity error
Processor APIC ID: 2

Does anyone know what the issue could be?
