op your Gpu stopped working because of a driver error ... its very common and the reason Windows doesn't tell people to jump on the band wagon until drivers have been out for a good while
the only fix is to adjust your system
settings into something more stable and that normally means rolling back a few driver ed
Quaudphonics no one can help you because you didn't tell us your system specx... i also assume you didn't do a clean install between moving from EA to release [just a guess]
