Question Powerbutton no longer works

[Tommelom]

Suddenly pushing the powerbutton no longer turn on the pc. I have tried directly connecting the -/+ powerpins, but nothing happens. So it's not the button. Jumpstarting the psu is not a problem either. The only way to start the pc is to quickly turn the powerbutton on the psu off an on.

Sounds like something flaky on the motherboard, or possibly PSU. If you have a spare PSU, you could try that in testing. That said, Z97 boards are starting to get older now and may devolop some quirks or issues going forward, or could fail outright.
