Solved! Entering bios during PXE-MOF error.

[hamilton.m.scot]

My Asus keeps scrolling the exiting PXE message over and over. And I am unable to open the BIOS menu to change the boot order

If you can't even get into the BIOS that is a sign it's a bad motherboard, are you sure your are hitting the right key and at the right time?
