Hello, I had the components in an open-air case and now I have moved them to a Cooler Master K350 but it won't turn on. Before there was a small led that turned green when the PSU was on "1" but now it doesn't turn on and neither does the pc which I think is because of the PSU. I didn't do anything different, I just plugged in all the components same as before...what can I do?
