Hi, I have just finished buying all my parts and putting together my computer. When I plugged it in and tried to start it up, the fans started to spin for a millisecond and then stop. So in my mind I feel like I have either hooked up something wrong or the motherboard is shorting out after the initial voltage.

any thoughts would be very helpful.
