I installed my brand new HD6670 in my CPU day before yesterday.
Then I installed the drivers from the CD that came with it.
Then I downloaded the updated drivers from AMD and installed them too.
Till now everything was absolutely fine.

After that, today, I installed the "AMD Catalystâ„¢ 11.10 Version 2 Preview Driver" and then, the whole screen turned black, except for the white objects (eg mouse pointer etc), which remained white. I immediately did a system restore.

Now everything went back to normal. I played a few games, and then turned off my PC.
After a few hours, when I switched it on, the DVI output didn't work...

So I now have to use VGA instead of that...
It happened after restart, so it seems to be a software thingy...
Thanks for reading my long post, and please help. :)

ok, you have to uninstall the current driver completely, and install the driver which came with the card.

Why use 11.10 version? Use latest 12.6 version. Before installing a driver always uninstall the old one then install new driver.

All fixed!
I just removed the DVI cable from both sides (monitor and GPU) and then after about 1 minute, re-inserted it, and VOILA! it worked! :) 
Now I have have installed the v12.6 too...
Thanks for helping guys!
