Just this week, I started to notice my Z77 Extreme 6 skipping the ASRock POST screen and going straight to the Windows boot screen whenever I restart Windows or press the reset button on my case (i.e., it no longer responds to the F2 button this way). Now I only see the POST screen whenever I shut off the machine and turn it back on, and only this way I can get back into my UEFI by way of the F2 button.

Did I just blow a capacitor or circuit on my board?
