A:Answer My PC came configured so that everything went to the 128gb SSD, which is designated as the C: drive. Nothing (programs, pictures, documents, music ) was sent to the 1tb HDD set as the D: drive. Check where your stuff is loaded. You may want to verify where your programs and data are stored, and move them off the C: drive.
There is also a "recovery drive" E:, that's only 16 gb; that may be where your programs installed and are running out of space. I don't know if it is a separate memory, or a partition on the SSD or the HDD.
