so a few days ago i got an new cpu cooler (coolermaster hyper 212 evo). my computer was working fine until i changed my cooler. we i tryed to start my coputer all the fans and lights inside my case worked fine but nothing happend on my screens so i changed back to my old cpu cooler and then it started working again. at this point i calls support to se what could be the fault. all they said what to change back to the hyper evo and se if it worked again, but it was all the same again. we tryed to reset CMOS but nothing worked so we changed back to the old stock cooler again and reseted cmos and it turned on. what can be tha case? those the backplate short my motherboard? can i try to buy and new hyper evo 212?
