PC won't turn on when case button is pressed
Had a previous issue which is located here:
Random freezes or BSODs (In windows drivers) - Windows 10 Forums
To tldr it was fixed by displaying all startup items and services.
Had a freeze today and after that when I turned the PC off (via case switch) it wouldn't turn back on again.
I tried different sockets and leads to no avail.
I performed the paperclip test which worked, and all voltages where ok (blue was -11.36 but thats been low for a while).
I then plugged everything back in and moved my attention to the power case button, and tested its connector to the motherboard and a voltage was present when and only when the power button was pressed.
I then tested the grey "POWER_OK" signal cable, which never changed when the power button was pressed, however this displayed a 5.1v signal when doing the paper clip test.
So then I tested the green "power on" signal cable, which showed 3.525v constantly, even when the power button was pressed, it was my understanding this should drop down to 0v, or at least drop when the power button is pressed?
If all my tests knowledge and assumptions are correct this means there is an issue with the motherboard from where it receives the power button signal to the 24 pin connector? If so what do I do next?
Thanks in advance for any help!
