A bought a hyper evo 212x a while back, never got around to install until recently. Once I installed I attempted to turn on the computer. However it won't actually turn on, the fans and light would turn on about 2-3 secs and then turn off, this process would repeat untill I physically unplug the computer. I've tried everything to resolved the problem, remove all unnecessary parts(GPU,extra ram, ssds and rgb lights) still won't work. Assamble everything on a cardboard box to see it was an issue of mb and case touching, nope. Followed the installation instructions to the letter and even watch a YouTube video. Gave up and install the stock cooler, it ran perfectly normal. I can't get a refund considering how much time has passed since I purchased it
