Stuck on ROG splash screen

sunjester · April 1, 2015

So I have an Asus Crosshair V Formula-Z and I'm seeing a somewhat consistent problem trying to boot past the ROG splash screen. It seems every time I do a cold boot it gets stuck on the splash screen, and to get it to boot I have to press the reset switch and suddenly it passes the splash screen and gets into the OS. Once I'm in the OS everything works perfectly fine and it's as stable as can be.

The other interesting thing is that a few times over the past week I've been seeing it get past the splash screen and displaying the message "Updating iROG firmware now! Do not shut off or reboot your computer until this process is complete.". It stays for at most 10 seconds and then another message flashes underneath that's too quick to read, then it resets.

I've tried clearing the CMOS so far but beyond that I'm not sure what to do. Outside of messing with the RAM clock I haven't touched the BIOS since I installed the latest update for it (version 2101) almost a year ago. Anyone have any ideas?

I was going to tell you to update your bios, but considering you already did that, and these aren't problems caused by bad bios settings, im not really sure what to say...

You would think weirdness like this would mean the whole motherboard is bad, but since it works in windows, its very strange...

Here are some ideas you can try. Most of this is just trying to emanate as many factors as possible. So if you don't need it to run your computer I would unplug it. Down below are just a few ideas of what I would check

- don't have any thumb drives plugged in, including any external hard drives.

- Did you try and toggle the fast boot option?

- Check the BIOS chip and look for physical damage.

- Also double check the BOIS setting and make sure your CPU is set to run at factory settings.

- Check the boot order

- unplug all sata ports that are not needed for boot.

If all else fails and you still don't have any answers you could re-flash the BIOS and hope that fixes it.

Adding onto that, if the motherboard has a debug led, see which number it stalls on. Most asus motherboards also have a boot splash screen time setting, and try setting that to +0 secs
