The space only disappears if the drive is dying and good space is used by data from a blocked bad clusters. In your case the free space wasn't / isn't disappearing. The free space is used by virtual memory (huge) or by temp files, browser cache etc.
Virtual memory is only used when physical (RAM) is all in use and you load another application that requires RAM. In this case, Windows move some amount of data from memory and save on the disk (much slower than RAM) freeing RAM for the application you want to load.
8G is a lot of memory and probably you rarely use more than half, but if you load many programs or applications at same time you may need more RAM and you make use of virtual memory as I explained above.
If you let Windows manage the size of the virtual memory, the virtual memory size will vary as needed and you will see the free space decreasing and increasing.
To avoid the the virtual memory size variation and as consequence the free drive space, I suggested you to set virtual memory to twice the size of the physical memory, that should be more than enough for normal use. Now you should only see free space decreasing as consequence of temp files, browser cache etc. Once you run Disk cleanup (to clean Windows) and CCleaner (to clean browser cache) the free space should return to normal.
If you set to a fixed value as the minimal you may experience freezing and or stability when windows needs more RAM.
