i was booting my system and then i closed my computer. when I press power button it turns on for like 3 sec and closes. I have a black screen. I tried many different things like taking out the ram and then putting it back on. Plugging off the power. Putting different hhd's and ssd's. What should i do? I know taking things out wont do anything and buying a new psu because the psu fan is running on its own.
