BIOSTAR N68S3+

I have a BIOSTAR N68S3+ MB and my friend recently bought a new GTX465 off of the forums. I swapped out my GTS450 with the GTX465 and everything worked great. Downloaded the new drivers. Ran a furmark on the Card. Overclocked the card. Friend was very pleased with the performance. I switched back to my GTS450 and the monitor will not go on. i tried his card again same thing. I tried the onboard video with both cards pulled and still can not get a picture. Is it possible that overclocking the videocard Blew up my Motherboard?
