Question Motherboard lights up but nothing starts

Yesterday I finally decided to put in my h150i pro water cooler as I've had it for a while but never got around to putting it in, after it was finally installed I plug in the power supply and I get the usual blue lights on the my motherboard but can't get anything to turn on. After a while of trying different things I decided to go back to the stock cooler to see if that was the issue, and I decided not to plug everything in again as I didn't want the hassle of plugging it all in just for no reason, so I only used the cpu, cpu cooler and ram (as well as case wirings) and I got the same issue, power is going to the motherboard but nothing turns on. All the parts were working the day before and the only difference is the motherboard got a slight scrape that doesn't look nearly deep enough to cause trace damage but everything I've tried seems to have no effect, any help would be appreciated
