Welcome to the forums. Sorry you're here because of an issue like that. It feels like the world is coming down on your shoulders when your first computer part dies and it happens to be expensive.
Your card is dying. There's no doubt about it. It sucks that BFG Tech went out of business, too.
It happens. My 8800 GTX died after 2 years of use, and my replacement 9800 GTX+ died after only one year. That 8800 GTX cost me $570 new, and it died. It sucks, but that's computer tech for you. The only saving grace was that it did have a warranty on it and I was able to get a replacement.
All you can do is buy a replacement card. Pay attention to the warranty period, and buy a card for a company that is stable and been around for a while so that if it does die, you can get a replacement for it. Get a warranty for the card that matches the length of time that you intend to use the card.
Good luck bud. Hopefully you won't have an experience like this again.
