fffffa8006b8caf0 doesn't look like a valid small pool allocation, checking to see
if the entire page is actually part of a large page allocation...

The pool allocation within the pool page which has caused the corruption, this a file object, a file object can either correspond to a I/O device or a open file.
The I/O device seems to more likely due to other errors earlier.

The current thread has attempted to free a pool allocation which has already been freed, we can see from the call stack the general process of freeing a object.
Other bugcheck is same as the other one in my last post:

Have you checked for any BIOS updates from your motherboard/model support page? Ensure if your going to update the BIOS, then you make sure you update with the BIOS version directly intended for your motherboard, as you irreversibility corrupt your BIOS.
