Welcome aboard, Nick.
A PC will not go to hibernate in some situations like ....
► If there is not enough Space in the C Drive.
Let us see....
Description Local Fixed Disk
File System NTFS
Size 465.66 GB (500,000,878,592 bytes)
Free Space 34.18 GB (36,698,836,992 bytes)
That's really low. You need to salvage some free space. Try it:
Hard Disk Space - Free Up and Recover
► If the Hibernate is disabled.
Then it is enable it. Follow the tutorial to enable it:
Hibernate - Enable or Disable
► If the hibernate file is damaged.
First disable hibernate
. Then run Disk Check
, and then enable it
Let us know the results.
