Re: I think I'm about to lose $1500...
What is your psu wattage and amps? We can't tell for sure without knowing that. However, I would say that it's a safe bet that you need a new psu, almost always the culprit for problems after adding a new GPU (in fact, my new graphics board caused problems until I added a new psu as well, and then everything was fine.) I don't know what you need to power your components, but I would probably suggest something like this:

This is a steal right now. Bought one myself, and for 30 dollars, it could save your entire rig. I would not continue running the computer without buying a new psu; when they fail, they have been known to take out other components along with, such as mobo or ram. Those are things you do not want to die. However, I would like to know what kinds of things you are running (eg. processor, ram, drives, peripherals) before I recommend a specific model.
