I'm really stuck. Building a new pc shouldn't be this difficult (i thought)
I keep getting bios splash
I can get into the bios and see the cpu, ram, disk drive, any usb that i connect to it.
I had created bootable windows 10 usb from windows tools, rufus, balena etcher, and aomeibackupper from 2 different computers. Used 3 different USB's stick over 8GB and plug on all the ports and even try installing Linus thru usb. Also, even tried booting windows from internal SSD.
At first I thought it was a faulty motherboard so I got another (Asus B450-i) and it is also having the same issues.
No matter what I do, it will always reboot, shows motherboard logo and bios options (f2, delete, etc) and continues loop.
I had even try removing the cmos and nothing , and force boot usb.
Please help....

First get the latest bios version directly from your bios net option (works well).
then load default settings and disable CSM bios option and also all the wifi/5G/Bluetooth onboard devices if you have these included on your mainboard. Also unplug all external usb HD. Save it and reboot.
Worked for me.
