Bottle necked storage

Hey, i have this problem. I just build a pc and on my 500GB hardrive only has about 100-200 GB of avaliable storage is there any way I can fix this.

Local Dick (c;) 15.3 Gb free of 75.9 GB
System (D;) 166 MB free of 198MB
Recovery (E;) 2.79 GB free of 20.8 GB
HP_TOOLS (F;) 98.9 MB free of 99.0 MB 

I am on windows 7. Thankyou

Go into File Explorer. Right click on 'Computer' and select Manage. Go to Disk Management. There you should be able to see all the partitions of your hard drive, or the lack thereof. If all that space is unallocated, you should be able to select you local disk (C) and expand the storage so it fills the rest of the disk.

Thanks a ton man That worked.
