Hi there Enki12,

You should go to Disk Management, and see whether you have unallocated free space. If so, right click on it and allocate it. Keep in mind that the unallocated space should be on the right and next to the partition you want to expand. If it is on the left, you will need to use to use some third party partition manager tool.

Hope this will help,

So, what are the partitions over there?(Do they add up to 900 something GB)
Also, you can go to BIOS and see whether the full capacity is recognized over there. If it is not, there may be something wrong with the HDD itself. If it shows the correct size, then you can back up your data and reformat the drive.
It may be a good idea to run a malware scan as well.
