Computer won't turn on anymore, worked fine Yesterday.

Hi,

Computer worked perfectly fine yesterday night, closed properly. But this morning it would not power on anymore. Only the USB outlets seem to be working as my mouse and keyboard still have their LED on. Everything else is dead. This is a year and half year old build and Mobo and PSU are still under warranty, never overclocked the CPU.

Took the PSU out of the case and tried the pin test. Fan turned on, but this would still not rule out the PSU has the source of the problem. Right?

I don't have any LED on my mobo to tell me what the problem might be. I guess it's a thing with Micro-ATX not to put anything on them...

I don't have any spare parts to replace anything on the computer or to test it. So I am wondering if I will have to purchase a new PSU to see if it is the problem, than a new MOBO if the problem still persist.

The only thing I can say, I moved a few things on my power outlet yesterday to make place for my new Amazon Echo, I did not unplug the power supply or close the computer when I did that move. It would be crazy for this to cause such a big problem to my computer...

Any solutions before I purchase a new PSU is welcome.

Right the test you are referring to only tests that the PSU can power itself, not that is can handle any load.

canned diagnostic speaker rant
The diagnostic speaker is the motherboards main diag feedback device.
the motherboard may be telling you where the problem is.
my speakers have this plug

I use lamp wire but any stranded wire will do. literally any stranded wires. strip one end like so

attach the stripped end into the speaker spring clips on the speaker.
the other end of the wire should be trimmed like so the semi strip

by doing a semi strip the wire case is now the socket.
plug one wire to the first pin, and the second onto the fourth pin.
power on the system and listen for beeps

Thank you, just went and bought a speaker from Amazon. Too bad I just threw away some old earphones, could have tried to do something with them. Will update once I receive this small bad boy.

Also tried to open the computer via the MOBO with a screwdriver and switch the power button to my reset button in case of faulty botton, but unfortunately, nothing there neither.

PSU was the problem, bought a new one after testing the Mobo and confirming it was still working.
