So i recently water cooled my computer, which i think was a complete success. no leaks or anything. Everything worked fine before hand, but as i put everything back together the computer wouldn't turn on. It started flashing on and off and the power supply started making noises that sounded very similar to a car indicator. i tried a different power supply, same thing. it sounds like a power issues, but i'm not sure how anything could have changed. I've attached a video to show what i mean. I'm thinking something is shorting it out.
