Hello everyone,

This morning I had a strange experience with my computer, which has worked very well before.
When I pressed the power button, nothing happened. No fans, no lights, nothing. I pressed it a few times, tried pressing the reset button, checked the power cable, etc. Nothing happened.

Then, I went off to make breakfast, and when I came back the computer powered on without me pressing the button. The delay between the power up and the last time I pressed the button must have been 2-3 minutes easily.

From what I read, I think it might be an issue with the power supply? I believe it is 3 or maybe 4 years old so that would not be overly surprising. I just wanted to check if I had the right idea before going out and buying a new PSU.

Anything I can do to zero in on the problem and figure out just what component is having trouble? Could it be something other than the PSU?

Thanks in advance for the help.
