i recently decided to use a case that i had redone. i took the components out of an old working system just to use the new case. i added a new ps. when i went to boot nothing happened. none of the board fans spun or anything. the hd was spinning and the fans connected to ps worked but nothing from mobo. i was stumped so i gave a friend the case and a new mobo and i checked that it worked before i gave it to him by setting it outside of case on cardboard and putting power to it. but when he put the mobo in case he had nothing. any suggestions? could it be grounding out and giving me a dead mobo?
