Updated BIOS---> PC boots much slower, and BIOS interface stutters.

[sorrowhill9]

I am running ASUS Z170-A, had this board for 1.5 years no problem.

2 days ago i updated the BIOS from version 3007 to 3504. Now i am having 2 problems:

1. The PC boots much slower. It used to take 5 seconds, now it's 20 seconds. I observed the motherboard, the VGA led light up red for 3 seconds, then the Boot_Device led lights up red for 5 seconds, then the beep sound and it boots. It used to be just the beep sound and no led.

2. When i press F2 to get into the BIOS, the BIOS interface is now stuttering. It used to be smooth like 30 fps, now it's like 5 fps. And if i change settings, it wouldn't reboot, the Boot_Device led lights up red. I had to press the restart button on the PC to restart, and back to problem #1.

Is this a BIOS problem? Should i go back to the old version?

Thank you.

Perhaps try resetting the CMOS by pulling the battery for 30 seconds.

I also have this problem. Latest good bios for me is 3401. Any higher than that will cause troubles. Look at sata speed, data transfer dropped from ~550mb/s to 150mb/s on my ssd. Problem is higher when i load xmp profiles and do some OC.
