Complete-Segragated Install of DAZ 3d

Over the year and a half I've been working with Daz 3d...I've had my share of file structure problems.
I need to know how to completely wipe ALL traces of Daz from my computer..and re-install a completely segragated version.
I have a version at home...and one at work..
the work version is clean....no PostSQL problems...logs into account well.....all the Face Transfer and Smart content work fine..
Home version not so much....Un-fixable PostSQL error....Face Transfer refuses to access the required files to generate....However it DOES find the smart content..even with the PostSQL error.
I want to wipe EVERYTHING and figure out a way to partition the C: drive for just Daz....and KEEP it in the partion..as hard as it will tryr to get out...and it will try.
