Hi Jerry,
Based on your descriptions , we are still unable to advice you on your blue screen issues. Blue screens and unable to load windows could be due to a magnitude of problem.
Firstly, it could be power supply not supplying enough power to your card.
Secondly, it could also be graphics card error.
However, from the serial number given to us, this card is already out of warranty for more than 9 months. If you need to verify the issue of the problem, you may bring your graphics card down to our service centre for testing. But if it is found faulty, we will not be able to claim warranty for you for this card.
Sorry for any inconvenience caused.
