You said you spilled a little bit on it... Not in it correct? When you used your hair dryer did you have it on heat or just air? if you used heat then more than likely when you turned it on everything was simply over heating. Turn it off for a bit and then try it later. Can you take a picture of your pc, and use paint to circle where it spilled? Does your pc have a fan on top? if your pc was closed with the side on it and doesn't have a fan on top, then I doubt anything got on your graphics card. Post the pics of your pc, and let us see.
EDIT: Did you build it or buy it pre-built? Does your GTX970 have a back plate?
