My stationary computer which is about one year old just crashed and won't reboot. All i was doing was surfing the web. When i try starting it no lights, fans or any of the sort starts going. When i toggle off the PSU i hear a small click-ish noise but that's all.

I'm a real rookie regarding this stuff and i just hope that it isn't some sort of expensive short circuit but a broken PSU(which I don't get why it would be tbh but that's the only possible thing i can think of)

Do you guys have any idea of what I can do to test what's wrong or do I have to go to some store tomorrow? I'll leave the thread here and go to sleep since I have to work in a few hours. Thanks in advance!
