Question When booting my pc it doesn't show bios splash, then goes to black screen with cursor

[Warmanskyrim]

So I noticed recently for the past 3 or so days. When I booted my pc it will skip the bios splash, go straight to blue windows 10 logo with black background, then go into a black screen with cursor. To note this is when I first boot it up in the morning it will happen, then turn it off and on, and it boots bios and windows properly. No clue if it's a bios or motherboard or in general hardware issue. My motherboard is a z87-g41 PC Mate.

maybe you need to replace your coin battery. could be going to fast boot and not preserving your settings.
