Sounds like Windows is giving you a bad driver for the 4830. Make sure you download the latest driver from Ati, found here.
Install them before you reboot see if that helps.
Just to be sure, you downloaded the RC from Microsoft and performed a clean install? And so were clear your not trying to crossfire the two cards are you?

i did try the ati driver, Rc was from Microsoft and it was a clean install both times. just 1 card.
thank you

So the black screen happens when you have tried using both the driver Windows update gives you, and the drivers from Ati?
But the 3870 works fine? You could try booting to safe mode, uninstalling all the Ati drivers and boot with the 4830, or an earlier version of the Ati driver, say 9.3 or 9.4.

Did the 4830 work properly on the motherboard under a different OS? If the card is new, it could be your motherboard is rejecting the 4830 and you may need toLink Removed due to 404 Error to a newer version, but you need to be careful and make sure you read your manual on how to do it.

Sorry I shouldve added to make sure Windows is activated and run the Windows update after you uninstalled the drivers.

Maybe its a resolution problem, do you have another monitor to try with?

 

[Slim Man]

it was activated and no this is it on Monitor that was my next upgrade . hope Microsoft look here.

thanks again
