Okay so last night I did a case switch with my computer. I have built dozens of computers and never had any major issues and last night went smooth too. I didn't suspect anything was wrong, but when I plugged it in and tried turning it on nothing happened, and I mean this literally. I checked the front end connections just to be sure I didn't mess the power switch cable or something up, made sure everything was connected to the PSU correctly and then tried again and nothing. I then tried a different PSU and again nothing, is my motherboard or my CPU not working then?
