My system has been working normally without any weird symptoms, but today when I tried to turn it on, it didn't quite work. Right when I push the power button, the power LED comes on, the PSU fan and the HDD starts to spin, but it all shuts off about a second later, and continuously repeats the process a few seconds later. I haven't moved my system or taken it apart since the last time I used it, so I assume something may have gone bad. What do you think? Power supply?
