Windows installed on m.2 from old build but was planning a clean install anyway. Can't boot from m.2 or USB, I've even tried installing a dvd drive and can't boot from disc either. All show same symptoms after bios screen I get Asus logo and spinning dots then after about 30 seconds dots freeze and nothing happens, sometimes fans keep ramping up but only occasionally! Idol temps low 30s in bios even after 30 minutes mb shows code A0.
