Maximus XIII Hero - Extremely slow to post.

I suppose you're looking in the task manager on the start up tab for your boot times.

Not boot times. Only Post times. I am using a stopwatch on my phone to calculate the time it takes to get from pressing the ON button till I see the option (Del or F2) to enter the BIOS.

For some reason it's far longer than on any PC I've ever owned including other ASUS and ASRock boards.

I was hoping there might be a setting in the Maxiumus's BIOS to turn off checking the USB connectors for connected devices. Windows can do that once it launches. I tried turning off the USB checking but of course then it doesn't detect a mouse or keyboard and halts on the POST screen.

I will try turning off the CSM and see what if anything that tells me. Thanks for the suggestion.

This appears to be a bug with ASUS BIOS as I have found others reporting similar problems with other ASUS boards. There is no way this configuration should be posting slower than my Z-87 Deluxe. Will try to contact ASUS and see if I can get them to look at the problem.

I finally was able to solve this.

When I assembled the system I did not have a graphic card and was using the onboard HDMI and two DisplayPort (Thunderbolt) connectors to drive my 3 monitors. I discovered the problem when I finally found a GTX3060 for MSRP. Had it not been for this I never would have found the problem. I decided to move my USB 3.2 Gen 1 header to the lower connection so it would not be behind the GPU. The connector would not go in. Upon inspection I discovered a piece of black metal similar to what the heat sinks are made of lodged in the port. The piece of metal had shorted out several pins. Upon removal I had to straighten two pins as well. Not sure if I bent those when trying to plug in the header. But upon reboot the system booted in a timely fashion and after more than a month I have not had a slow boot since.

Fluke of an issue but I wanted to post a follow up just the same.
Had I not decided to move the header I never would have discovered this as I had never tried that connector.

It's always something.
