Right...I can’t install windows 10 back onto the drive it was previously installed on, After an update I was unable to get past the BIOS check screen. I’ve updated the BIOS, checked the hard drives (2 Seagate Barracuda’s), checked the RAM (x2 8GB HyperX Fury), AMD FX 4350, asus m5a78l-m-usb3 mobo. I’ve reset the CMOS and still nothing. It won’t boot windows 10,7,8 from USB or disk, it hangs as it starts to read the usb and stays like that for 3 hours (thought I’d leave it for as long as possible). So is it time for a new mobo? Any suggestions would be great!
