Newly built system won't power up
Hello, and thanks for helping me out! I just "finished" building a computer, my first one thus far, and I've run into quite a problem. It won't start! Nothing at all, no noises, fans, beeps, nothing. The only two things that are telling me it is working is that I get a blue light on my case when it's all hooked up, and when I flip the PSU switch to on, you can tell the lights just barely flicker. But nothing happens after that. I made sure to check my PSU by shorting pins... whatever they were, and the PSU's fan powered on and seemed to work perfectly. But when it's in the actual system, no dice. So, ruling out the possibility of DOA parts for my sanity's sake, any help please? Much thanks!!
