Updated driver & now GUIminer returns verification failed check hardware

[dementyev]

So I have an Radeon HD 6870.  I updated the driver by getting their latest Catalyst Control Center program and now when I try to mine with GUIminer I get this:

2013-05-12 15:26:14: Running command: poclbm.exe USERDATAREMOVED@yahoo.com:USERDATAREMOVED@pit.deepbit.net:8332 --device=0 --platform=0 --verbose -r1

I tried uninstalling the new driver and using older drivers, which resulted in utter disaster, got a MMdriver.exe has stopped working error with every one I tried (about 5!) and the screen display would go nuts and blip into a messed up color config that was so bad I could barely see my way back to the CCC uninstall.

Anyone got any ideas about what is going on and how I can fix it?

Oh also, I tried doing this:

And the 11.11 driver gave me hell: MMdriver.exe stopped working error, CCC crashed, & the display colors went bananas alternating between a mostly black display and a checkered red pattern.  Somehow managed to find the uninstall even with the messed up display colors and got it back to the latest driver which at least works (just not for mining)  @#%#$% ATI & their godawful drivers.

Anyone have any idea what is going on?

same problem here after updating to 13.4 drivers. uninstalled the APP SDK v2.8 and put back v2.4 and still have the same problem with my 5770 card.

I would recommend sticking with the old versions of ATI drivers. Also, if you are mining 24/7 with a dedicated machine, you should probably use cgminer vs. GuiMiner as cgminer is much more stable.

Update: I successfully installed CCC 11.12 & SDK 2.6, apparently what did the trick was manually deleting some of the dll files as suggested in this thread:

https://bitcointalk.org/index.php?topic=177855.0

So now the old drivers I installed are now more or less working properly (it still gave me an MMdriver stopped working error).  Fired up GUIminer and it started mining (at 30mhash/s less than it was before all this) but after 43 shares it fails, and the console reads this now:

Anyone have any ideas now?  Maybe there's more dll files from the latest driver/CCC package that I need to manually delete?

Maybe I need to go nuclear on the ATI driver files and manually delete them all?  Like in this thread:

I'm not mining 24/7 and I use the comp for other things so I went with GUIminer for ease of use.  So with cgminer you have to compile it yourself, there's no already compiled DL available or anything?

Tried a system restore to the other week when everything was working smoothly.  Same result as above, mines for a few shares then terminates with a long pole IO error.  So apparently there still some garbage from the update to CCC 13.4 still sitting around somewhere screwing things up.  Anyone know what all I'd have to do to totally clean out all the ATI driver files? 

So question for power users who really know their s***: I thought of searching for: *amd*.dll, *amd*.exe, *ati*.dll, *ati*.exe, *opengl*.dll, *opengl*.exe and deleting everything that shows up, would that work?  (my CPU is Intel so there are no other AMD devices aside from the GPU)  If not what all would I have to do to get rid of all ATI drivers & references to that may be screwing things up?
