Sometimes my asrock ze97xac doesn’t want to boot up and stays stuck at the asrock flash screen.
Another button press or reset press doesn’t change the outcome.
The following links explains to unplug all extras and try again. This never worked for me.
As my system is plugged into a power strip with indivise socket control I simply turn off the computer via the strip button then press and hold the power button.
Letting go of the power button. I switch the current to the system back on via power strip and press the power button once more.
Voilà. System booting into OS as normal.
it’s strange to have this error to start with but at least it’s manageable without messing around with unplugging all accessories.
