My 560ti is not working properly, it flickered the screen then blue screen then reset my pc and Whenever I enter window 7 start up, it just flickers and shut off. No matter what version of driver I installed, it does the same thing. It only works when there is no driver installed. Tried all the suggested driver versions I can find. Still no luck. Anyone have an idea of what could be wrong? I switched my other pc's gt 730 in it and everything looks fine. So i am sure it's the card.
