Display Issues

Hi,
So I just replaced my MB because is had been fried and when I put my computer back together I am not getting any output from my monitor. It is showing the message for no input but it will not show display from my computer. When I turn my computer on I can hear the beeping coming from the MB and everything seems to be working except for 2 things. The lack of output from my monitor and the fan on my GPU is not spinning. I am about 90% sure I need to replace my video card assuming that the fan went out, it fried, and in turn fried my MB. However, this is not my area of expertise and I wanted to get a second opinion before I dropped a couple of hundred dollars on a new GPU. Any thoughts?
Thanks,
E
