Hello, this is my first build and I fear I screwed everything up. I got all of my components in my case except for my Graphics Card because it has not come yet, but I wanted to see if my computer would turn on and I could just use the motherboards display ports for my monitor. Everything turned on including the motherboards leds but my monitor was not getting a signal, and neither was my keyboard. I was looking around on here for answers and the only thing I could find is that the mobo shorted, but I can't find where.

Anything helps, thanks.
 
#12 on that list could be the problem. When I was applying the thermal paste I was not getting any out so I added some force and a glob came out. I got a paper towel and dabbed it in the paste to get some of it off but a string of the paste got on the motherboard as I pulled the towel up. Should I try and clean it more?
