dun panic.. now if everything ok try enable other option.. rmb run regedit as admin & end process the CCC.exe & MOM.exe b4 edit regedit..

here's what you do, go into your CCC and head over to Information>Software

Copy the 2D driver Path to a notepad so you would see which registry to edit.

For some it maybe: :/MACHINE/SYSTEM/ControlSet001/Control/Class/{4D36E968-E325-11CE-BFC1-08002BE10318}/0000
For others it maybe: /MACHINE/SYSTEM/ControlSet001/Control/Class/{4D36E968-E325-11CE-BFC1-08002BE10318}/0001 etc.

Check CCC first.

Next, click on the start button and in the search box type the word: regedit. Select regedit by right clicking on it and select "Run as Administrator". Goto: /MACHINE/SYSTEM/ControlSet001/Control/Class/{4D36E968-E325-11CE-BFC1-08002BE10318}/000[X] (X denotes whatever CCC 2nd Driver File Path tells you) & locate and change the following (right click on it and select modify):
-Change MLF_NA from 1 to 0 (MLAA)
-Change SurfaceFormatReplacements_NA from 1 to 0 (Surface Format Optimizations)
-Change TFQ_NA from 1 to 0 (Mipmaping textures)
-Change EQAA_NA from 1 to number 0 (New AA called EQAA)
Now open up the UMD sub key located:
/MACHINE/SYSTEM/ControlSet001/Control/Class/{4D36E968-E325-11CE-BFC1-08002BE10318}/000[X]/UMD and add the following:
Right click, select new, select string value and enter: MLF_DEF. Then right click on MLF_DEF and select modify. Enter 0.
Right click, select new, select string value and enter: SurfaceFormatReplacements_DEF. Right click on SurfaceFormatReplacement_DEF and select modify. Enter: 0
Right click, select new, select string value and enter: TFQ_DEF. Then right click on TFQ_DEF and select modify. Enter: 1
Right click, select new, select binary value and enter: EQAA. Then right click on EQAA and select modify. Enter: 31 00
Right click, select new, select string value and enter: EQAA_DEF. Then right click on EQAA_DEF, select modify. Enter: 0
Right click, select new, select string value and enter: EQAAMapping_SET. Then right click on EQAAMapping_SET, select modify. Enter: 0(0:0,1:0) 2(0:2,1:2) 4(0:4,1:4) 8(0:8,1:8,2:16)

No need to reboot, just press the windows key and letter "r" to open the Run command, type in MOM.exe Restart. And then boom you are done!
