Windows 7 Kernal-WHEA Event ID 20 Error

Hello.

Recently I've been getting this error in my WHEA error list.
It doesn't feel like anythings actually happening when it occurs, but it happens during games.
I've got the latest drivers for everything etc and Windows 7 is up to date.


Any ideas?


Windows 7 64bit
Asrock z77 Extreme4
