Piece of defective hardware

I thought I've hit the jack pot and got this monster for cheap, but it was a nightmare . First day installed and it works beautifully for the first 2 hour; I turn off the comp and turn it back on and encounters a driver failure - screen went black. So I thought it might be a mistake during installation, but it was not. I reinstall the whole os and carefully install every software and driver smoothly; after 3 hours of usage, the samething happened - black screen. Amd does have history of writing bad drivers. Went to many forums and found out all have the same problem. Seems like this particular model is known to be defective - and other batches. I filed a rma already. Hope they'll credit me back and pay for the shipping! Extremely dissatisfying with this purchase; hope it does not mess up my newly build PC because I reinstall the os and other stuff over so many times. Bought thousands worth of stuff from here, first time an issue with a product like this.
