Catalyst Wont Open, aswell as occasional Crahses

Im running a 6870 with windows 7 64-bit
, for the most part i have had no problems with catalyst or the card, apart from a random occurence where the screen rolls over, so the left side goes into the right and it just moves to the left so it still covers the screen, HOWEVER
thats not my current issue,
i recently used 'Driver sweeper' to clear all AMD drivers and do a fresh install of the frivers/catalyst to see if i could stop the occasional "this driver has stoped responding but has been seccesfully recovered" rerroes, or this screen spiltting issue, because i presumed it was a software issue, and then i re-installed with the 11.12 version, which at teh end came up with a message that there were erros and to read the log, which i did and thety all said sucess with nothing down the bottom saying anything about an error, but it all still worked althoguh i still had hte not responding error
however i recently installed the 12.2 preview drivers, 9aswell as the 12.1 drivers), both of these version after i install them catalyst wont open, on both right clicking the desktop and running ccc.exe
after i installed it i havnt had any not responding or BSOD errors, however i cant acces catalyst, and on some occasions when i installed hte 11.12 drivers random things like not being able to acces catalyst via right-clicking the desktop happened, i have had a look at many posts about it not worknig or opening up ,but they all come back with a fixx where they just removed and installed it fresh, well i have triyed the amd uninstalled aswell as driver sweeper, both to no avail, and i have hte lates .net framwork to support catalyst, i just dont understand why it wont work
and now when im trying to acces catalyst explorer comes up with the not responding error, and i can see catalyst in the task manager pop up for a second but then it goes away, i will check msconfig and services to make sure its all working but i cant think of any reason why it wont work at all

i checked both and its all working fine there, confusing
please any insight from someone would be greatly apreciated

The only suggestion I can make is to uninstall the DRIVER from device manager, then boot into safe mode by tapping F8 at startup and run Driver sweeper from safe mode. Then boot back into windows and install CCC. As far as the error messages and no errors in the log file, that is pretty common, at least for me.
