Thank you for the feedback. I realise that I did not include much specifications in my message, this is due to the fact that I copied and pasted my message from the support site where all these were part of the pre requisites...
I7 940, Asus P6T Deluxe, 4GB RAM, Radeon 4870 PCi 1GB VRAM, Windows XP 32 SP3. Moving to CCC 12.6 and driver version 8.970.100.3000 (I did not take note of the previous version).
In safe mode I could roll back to a saved situation where I had uninstalled the ATI driver and CCC.
There in Device Manager it says that my VGA card is not configured properly (code 1) I see that a non identified driver is installed on a VGA compatible card (not identified yellow question mark next to it), should I uninstall this VGA driver as well or is it the only "stock" driver that will allow access to my computer?
Below that my VGA card, there is another graphic card identified as BB capture driver, I never touched that one, should I also uninstall it?
In advanced display parametres, the card is not identified, clicking on Properties, I see that the pilot is VGASave, so presumably I should not touch that if I want to have the default display that I am having presently in low definition.
Now looking at my C drive, there is an AMD folder in which I started the CCC uninstall tool, it tells me that there is no ATI components installed, but why then is there this folder with the 12-6 legacy XP 32 list of components including the driver, in the Windows uninstall, there is nothing from AMD/ATI, should I remove them manually? Interestingly neither CCleaner nor Driver Sweeper found anything to delete.
To save time, I removed them manually, so now my system has no more reference to AMD/ATI software anywhere confirmed by Driver Sweeper, CCleaner and Auslogics registry cleaner.
I rebooted.
From this "clean" situation, I re-installed CCC from scratch and the conclusion of the install was a yellow question mark, I opened the report and found that everything installed successfully and at the bottom of the page I found "No error". I rebooted again and... black screen!
So this shows clearly that something somewhere remains in my system.
UPDATE:
After doing the above, I run Driver Sweeper again and realised that a number of ATI entries were still there. I removed all of them, closed Driver Sweeper and reopened it, to see that all ATI entries were back!!!
I am running Windows NET 3.5, so there is no question about being able to run this software properly, why on earth am I not able to clean these ATI entries, I believe my problem is here. Any advice would be welcome.

Thank you to please clarify.
