Overclock gone wrong... help!

[thecremeegg]

Right I tried to increase the overclock on my 4870 but it failed and I got massive screen corruption and then grey, requiring a reboot.
The problem is that now if I load into windows I can't get into CCC without the same corruption! I can't work out how to stop it as in safe mode CCC won't load!

Any ideas?

Yep, and its still the same, has seemingly saved the oc to the card or something

I'm in windows now having uninstalled and reinstalled the ATI 10.4s. If I try and load CCC then it all goes wrong and artifacts

Edit: Andy, what do I need to delete from the registry? Cheers

try a driver cleaner program??

Have heard these cause trouble?

put the card is a diffrent pci-e slot and change the overclock and then put back in original slot

Only got one slot

In the end I used driver sweeper, which on its own didnt sort the problem. I had to download rivatuner and use that to set the clocks back! I must have rebooted over 20 times tonight, not a process I want to repeat!
Thanks for the help guys
