video dxgkrnl fatal error

I have a Concept D 3, and I keep getting the BSOD video dxgkrnl fatal error. 

I have used DDU to remove the video drivers completely, about 20 times. This used to work for about a week or so, but lately, nothing other than reinstalling windows gets me to be able to use my video card. 

I have a minidump file if that would help. 

Any ideas would be greatly appreciated.
